Canine Cognitive Dysfunction Syndrome and Prevention
March 30, 2024 / General Health / By Dodds
Canine Cognitive Dysfunction Syndrome (CCD) is a gradual and common degenerative disease in dogs due to changes in the brain.
Four decades ago, we would have thought that CCD is a part of “the normal aging process” in a companion dog. It can be. However, research has revealed that CCD is analogous to dementia or Alzheimer’s Disease in humans.
Similar to other degenerative diseases like osteoarthritis, CCD is the interplay of genetics, environment, nutrition, and lifestyle that continues to be unraveled. Fortunately, research has given us diagnostic tools, signs, and treatment options to delay or lessen disease progression.
Signs of CCD
Signs of CCD can be so gradual that companion pet parents may not even notice them because they adapt to them or excuse them.
- Disorientation
- Behavioral changes – ex. irritability
- Interaction – ex. nonrecognition of familiar people or pets
- Sleep pattern changes
- House-soiling
- Activity level changes
- Anxiety
- Learning changes
Of course, the signs could be due entirely to something else. For instance, house-soiling. Did the companion dog’s environment change due to a move, urinary tract infection (UTI), weather, addition or loss of a companion, new baby or child in the home, CCD, or a combination of two or more? Fortunately, tests are available to gauge the level of CCD.
Testing
Hemopet’s CellBIO test does not directly diagnose cognitive decline. CellBIO measures cellular oxidative damage, which has been proven to be associated with cognitive decline.
Veterinarians will also need to rule in or out other potential causes of the signs such as UTIs or hypothyroidism, and have a few other tests available to diagnose CCD such as the Canine Cognitive Dysfunction Rating Scale (CCDR) or Canine Dementia Scale (CADES).
Both of these tests rely on observations, which can be subjective. So, the best method is to complete one of the tests every six months or so on any dog of any age (particularly seven years or older). You can do this at home. Doing it on a scheduled basis instead of daily or weekly gives the room needed to account for seasonal changes, or “good days” and “bad days.”
The researchers that developed CADES performed comparisons every six months to validate their test. Sadly, they found that the rate of conversion at the 6-months follow-up of normal aging to mild cognitive impairment was 42%, while conversion rate of mild to moderate cognitive impairment was 24%. At twelve months, the conversion rates almost doubled to 71.45% and 50%, respectively.

Treatment of CCD
No cure exists for CCD, but there are many tools available to slow its progression.
Prescription Medications – There are prescription medications available. Instead of resorting to those immediately, talk to your veterinarian about trying the other methods mentioned below.
Activity, Activity, Activity! – We cannot stress enough the need for physical activity such as a walk and interactive toys.
Diet –
- Leafy greens (supply folate, vitamin B- 9) – kale, spinach, collard and mustard greens
- Cruciferous vegetables (supply folate, carotenoids) – broccoli, cauliflower, bok choy, Brussels sprouts
- Beans/legumes (supply choline)
- Whole grains (gluten-free = quinoa, millet, rice, soy, corn, flax, TEFF, tapioca)
- Berries/cherries (supply anthocyanins, antioxidants, vitamins C and E). In fact, you can use them as treats.
- Omega 3 fatty acids (are anti-oxidant, anti-inflammatory) – Fish oil is an example. We prefer smaller fish such as sardines and anchovies. These fish do not have a build-up of mercury in their systems. The high DHA contains higher concentrations of vitamin E, taurine, choline, and l-carnitine, which can also play a positive role in healthy cognitive function. Whatever fish oil you choose, please ensure your companion dog does not have a food sensitivity or intolerance to it as revealed by NutriScan.
- Yellow squash, asparagus, tomatoes, carrots, beets (supply folate, vitamin A, iron)
- Nuts (supply omega fatty acids, vitamins E and B-6, folate, magnesium); but not macadamia, walnuts, hickory nuts or black walnuts, pecans and Brazil nuts for dogs
- Seeds (supply zinc, choline, vitamin E)
- Spices (are anti-oxidant, anti-inflammatory; eg. turmeric)
- Herbs such as Ashwagandha, an anxiolytic to help reduce chronic stress
Supplements –
- Alpha Lipoic Acid – Hemopet’s proprietary blend, BioBlend Super 6, contains alpha lipoic acid.
- Medium-Chain Triglycerides – An excellent example of this is unrefined, expeller pressed coconut oil. The agreed-upon amount to start is 1/4 teaspoon for dogs less than 15 pounds and 1 tablespoon for larger dogs. You will need to balance coconut oil for weight management. If your companion dog is doing well and not exhibiting any side effects such as diarrhea and weight gain, the standard threshold is 1 teaspoon per 10 pounds of body weight per day. Coconut oil is high in fat and can cause diarrhea if too much is given.
- Melatonin
- S-Adenosylmethionine (SAM-e)
- Phosphatidylserine – Is found in many cognitive support blends. Two well-known examples are Senilife and Aktivait.

Maintenance Ear Cleaning
Whole Dog Journal Editorial Staff – March 20, 2024
Holistic veterinarian Stacey Hershman, of Nyack, New York, took an interest in ear infections when she became a veterinary technician in her teens. “This is a subject that isn’t covered much in vet school,” she says. “I learned about treating ear infections from the veterinarians I worked with over the years. Because they all had different techniques, I saw dozens of different treatments, and I kept track of what worked and what didn’t.”
Maintenance Cleaning
Dr. Hershman’s healthy ears program starts with maintenance cleaning with ordinary cotton balls and cotton swabs. “This makes a lot of people nervous,” she says, “but the canine ear canal isn’t straight like the canal in our ears. Assuming you’re reasonably gentle, you can’t puncture the ear drum or do any structural damage.”
Moisten the ear with green tea brewed as for drinking and cooled to room temperature, or use an acidic ear cleanser that does not contain alcohol. Dr. Hershman likes green tea for its mildness and its acidifying, antibacterial properties, but she also recommends peach-scented Derma- Pet MalAcetic Otic Ear Cleanser or Halo Natural Herbal Ear Wash.
“Don’t pour the cleanser into the dog’s ear,” she warns, “or it will just wash debris down and sit on the ear drum, irritating it.” Instead, she says, lift the dog’s ear flap while holding a moistened cotton ball between your thumb and index finger. Push the cotton down the opening behind the tragus (the horizontal ridge you see when you lift the ear flap) and scoop upward. Use a few dry cotton balls to clean out normal waxy buildup.
Next, push a Q-tip into the vertical ear canal until it stops, then scoop upward while rubbing it against the walls of the vertical canal. Repeat several times, rubbing on different sides of the vertical canal. Depending on how much debris is present in each ear, you can moisten one or several cotton balls and use two or more Q-tips.
“You don’t want to push so hard that you cause pain,” she says, “but for maintenance cleaning using gentle pressure, it’s impossible to harm the eardrum. I refer to the external ear canal as an L-shaped tunnel, and I tell owners to think of the vertical canal as a cone of cartilage. People are always amazed at how deep the dog’s ear canal can go. I often have them hold the end of the Q-tip while I demonstrate cleaning so they feel confident about doing it correctly without hurting their dogs.”
If excessive discharge requires the use of five or more Q-tips, or if the discharge is thick, black, or malodorous, Dr. Hershman recommends an ear flush.

6 Household Items Toxic to Dogs
from the Whole Foods Journal
By Editorial Staff Published:February 9, 2024
This probably goes without saying, but always keep potentially harmful items in closets, drawers, or cabinets that your dog can’t open, not on a table or countertop or in a bag left on the floor. Make sure your kids understand these rules. And always supervise your dog’s play indoors and out. A curious puppy or dog can quickly find a way into even items that seem harmless — but can actually be quite harmful to pets. Here’s a rundown of common things you might have in your home.
- Xylitol. It’s a low-calorie sweetener that is derived from birch trees. It was first created in Finland during World War II, when sugar supplies were interrupted. Xylitol has a lot of dental benefits for humans, including the prevention of cavities, dental plaque, dry mouth, and bad breath. It also has the unique ability to remineralize tooth enamel. You can find xylitol in candy, nasal sprays, mouthwash, gum and as an artificial sweetener. Dogs, however, should not consume xylitol. In dogs, xylitol causes a rapid drop in blood sugar. This can cause seizures in dogs, which sometimes lead to death.
- Chocolate. While the rule that the darker the chocolate, the healthier it is may be true for people, the opposite is true for dogs. Chocolate’s problem ingredients are theobromine and caffeine, which dogs absorb through their gastrointestinal tracts too fast and put damaging stress on the liver. In dark chocolate, these naturally occuring ingredients are more concentrated and are likely to lead to serious problems, death included. Note: Cocoa powder, in some cases, can be as concentrated as dark or baking chocolate. Even cocoa bean shell mulch, a popular garden product, can be toxic when swallowed by chocolate-craving chow hounds.
- Grapes and Raisins. The toxicity of grapes to dogs is still not really understood by scientists. Reactions vary from dog to dog. Some dogs can eat grapes regularly and never have problems. Accidentally eating a few grapes probably won’t affect a dog of any size. But when ingested in siginificant quantities – as little as 2.5 ounces – this fruit can cause kidney failure.
- Onions. Onions and their cousins, garlic, are rich in a compound called thiosulphate, which is toxic to dogs. Being much more thiosulphate-potent than garlic, onions pose a threat to dogs if they eat just a single serving – about one good-sized onion. Thiosulphate causes hemolytic anemia (“Heinz factor”) in dogs, a condition that bursts red blood cells. Symptoms of hemolytic anemia can develop in a range of time – generally within a few hours, but can also be after a few days. Signs of hemolytic anemia include depression, weakness, no interest in food, vomiting and diarrhea. In a progressed case, the dog’s urine will become red from dam-aged blood cells. As oxygen-carrying red blood cells die off and leave the dog’s body, the dog becomes suffocated.
- Garlic. Garlic is a tricky one because when used topically and sprinkled over food, it is great for dogs. It fights ear infections, internal infections, boosts immune systems and lowers blood sugar. But it also contains thiosulphate. Many holistic veterinarians and health care experts believe that feeding doses up to 1 small clove of garlic per 20 pounds of body weight per day are not likely to pose problems for dogs. When uses topically for wounds or ear infections, it is harm-less. If your dog were to eat a whole head of garlic, on the other hand, refer to the earlier section on onions.
- Macadamia Nuts. The good news is that we have no documented cases of macadamia nut poisoning that has led to death. It alleviates after it passes through the dog – in around 12 to 36 hours. The bad news is symptoms are dramatic. Hind-end weakness, lethargy, depression, vomiting, and diarrhea all come after eating as little as 1 gram of macadamia nuts per pound of a dog’s body weight.

PROTECTING PUPPIES FROM PARVOVIRUS
VMBS NEWS — March 28, 2024
Springtime brings a vibrant burst of life and marks a time when many puppies are born.
As a result, the spring also presents peaks in canine health concerns that can impact puppies in the months after they are born. Among these is parvovirus, a highly contagious and potentially deadly disease.
Dr. Kathleen Aicher, an assistant professor at the Texas A&M School of Veterinary Medicine & Biomedical Sciences, explains why parvovirus is so contagious between dogs, emphasizing the vulnerability of puppies and how crucial vaccinations and treatment are in preventing the infection from spreading.
The Role Of Parvo Vaccinations
There are several factors that make parvovirus a highly contagious infection that can be fatal without prompt and intensive veterinary care.
“Parvovirus is very easily transmitted between dogs because it takes very little exposure to cause infection, and dogs who are infected can shed the virus for a few days before they exhibit symptoms, unknowingly exposing other dogs to the virus,” Aicher said. “The virus is also very resistant to extreme temperatures and cleaning, so it can remain in the environment for a long time, putting dogs at further risk.”
Parvovirus is especially dangerous for puppies, who have weaker immune systems compared to adult dogs and are highly susceptible to parvo until they are fully vaccinated.
In fact, most puppies and dogs that get sick with parvovirus either have not been vaccinated or have not yet completed their vaccination schedule.
“Puppies may get some initial parvovirus protection by antibodies from the mother, if she is vaccinated, but it is unknown how long this protection might last,” Aicher explained. “For these reasons, there are well-established vaccine schedule guidelines that veterinarians follow to keep puppies protected during the time that they are most vulnerable to infection.”
Vaccinations against parvovirus — which have significantly reduced the number of infected dogs — should initially be given by veterinarians when puppies are 6-8 weeks old, followed by boosters up to 16-20 weeks old.
Until they are fully vaccinated, Aicher encourages owners to keep their puppies away from areas where dogs congregate, such as dog parks, doggy day care, boarding facilities, and pet stores, particularly if they are displaying any signs of illness.
“If owners want to begin training their puppy in a class with other owners and puppies, they may be able to find places in which there is a policy of only allowing healthy, vaccinated puppies and that practice effective and regular disinfection of the facility,” Aicher said. “Owners might also bring their puppy to spend time with fully vaccinated, healthy adult dogs who belong to friends or family members.”
Battling Parvo With Veterinary Care
Despite the effectiveness of vaccines, owners should remain aware of parvovirus symptoms, as early detection and treatment can make a significant difference in recovery for puppies.
“Parvovirus is always suspected highly for any suddenly sick puppy, regardless of vaccination history, and any such puppy should see their veterinarian right away,” Aicher said. “Classic symptoms of parvovirus include severe diarrhea, particularly with blood or a very bad smell. Puppies may also be vomiting, have a poor appetite, feel warm or very cool to the touch, or act lethargic and weak, with very low energy.”
Because of how infectious parvovirus is, Aicher advises owners to contact their veterinarian before bringing in a sick puppy for an appointment, allowing the veterinarian’s office to take precautions that protect both the puppy and other dogs in the hospital.
“Many veterinary hospitals will treat any sick puppy as a parvovirus suspect until proven otherwise, which means they might wear protective gear, use a special exam room, or want to test your puppy for parvo before bringing them into the hospital,” Aicher explained. “The typical test for parvovirus is very easy to perform and results can be obtained very quickly.”
Veterinarians will then discuss the diagnosis in more detail and share their concerns based on the puppy’s history and physical exam. Aicher noted that, frequently, infected puppies will need to remain hospitalized for supportive care until they recover because of how sick they can become.
Despite the dangers of parvovirus, the impact of the disease can be reduced with proper vaccination and swift veterinary care, ensuring that puppies grow up healthy and happy.

What Is a Veterinary Behaviorist?
The best in health, wellness, and positive training from America’s leading dog experts
By Pat Miller, CBCC-KA, CPDT-KA – Published: March 2, 2024
When neither your dog trainer nor your veterinarian have been able to solve your dog’s problem behavior – such as aggression, extreme fear, obsessive/compulsive behavior, or separation anxiety – a consultation with a board certified veterinary behaviorist is advisable.
All experts approach problems from the perspective of their education and experience. Given a dog with problematic behavior, a trainer may recommend equipment changes, behavior modification, and management steps. A veterinarian may prescribe medications that reduce anxiety and increase social behavior.
Aggression, self-mutilation, phobic or extreme fear, obsessive or compulsive behaviors, and severe separation anxiety are the behaviors that most frequently prompt a consultation with a veterinary behaviorist.
However, behavioral problems can result from neurochemical imbalances, medical conditions, past life experiences, current living conditions, and every combination of these. Veterinary behaviorists are uniquely positioned to use tools from both medicine and behavior science to most accurately diagnose and efficiently treat dogs with severely problematic behavior, such as aggression, self-mutilation, phobic or extremely fearful behavior, obsessive or compulsive behaviors, and severe separation anxiety.
One of the most valuable benefits of working with a veterinary behaviorist is their extensive knowledge of how psychotropic medications can further your dog’s behavior modification program. (By law, only veterinarians can prescribe or give you prescription medication for your dog.)
Some owners are resistant to using behavior medication for their dogs. Sometimes their resistance stems from working with a veterinarian who wasn’t experienced enough with behavior-modifying medications to tweak the dog’s prescriptions for the best results. The client’s dog may have been given medication that was too strong (“I don’t want my dog to be a zombie!”) or too weak (“It didn’t do anything!”).
This is sad, because often medication can make the most impactful contribution to improving the dog’s quality of life. In many cases, the right medication(s) can make a good training professional’s behavior-modification program much more successful, much sooner. If you are working with a skilled training professional, the addition of the right medication might make the visit with the behaviorist unnecessary!
But if neither your trainer nor your vet have answers to your dog’s challenging behavior – or when they are failing to work together to provide an all-encompassing treatment plan for your dog – a consultation with a veterinary behaviorist is well worth the cost.
THE TERM “BEHAVIORIST” IS IN WIDE BUT VARIABLE USE
Would it surprise you to learn that literally anyone can call himself or herself a behaviorist? The title means nothing. There are any number of dog trainers – qualified and unqualified, educated and uneducated – who call themselves behaviorists. However, here are a few titles that include “behaviorist” that actually do mean something:
-Veterinary behaviorist. Only licensed veterinarians who have been certified by the can use the title of veterinary behaviorist. The formal term is Diplomate, American College of Veterinary Behaviorists (DACVB). You can find veterinary behaviorists at dacvb.org/search/.
-There is another professional organization that has “veterinary” and “behavior” in its title – the American Veterinary Society of Animal Behavior (AVSAB) – but it does not provide certification of any kind. Veterinarians and persons holding a PhD in animal behavior or a related field may join this membership organization, but it does not confer certifications or presuppose a level of expertise in animal behavior. Behavior consultants who are members of AVSAB are listed on its website (avsab.org/directory/).
-Certified Applied Animal Behaviorist (CAAB) and Associate Certified Applied Animal Behaviorist (ACAAB). These are scientists, educators, or other animal professionals with advanced academic backgrounds in the principles of animal behavior. Certification for these titles is provided by the Animal Behavior Society, which describes its certificants this way: “A professional applied animal behaviorist has demonstrated expertise in the principles of animal behavior, in the research methods of animal behavior, in the application of animal behavior principles to applied behavior problems, and in the dissemination of knowledge about animal behavior through teaching and research.” You can find these professionals at animalbehaviorsociety.org/web/committees-applied-behavior-directory.php.
-Certified Dog Behavior Consultant (CDBC) and Certified Animal Behavior Consultant (CABC). These certifications are bestowed by the International Association of Animal Behavior Consultants (IAABC), which offers animal credentialing examinations for several animal species and specialties. Obtaining a CDBC credential indicates a superior level of knowledge as well as skill in practical application of behavior change principles following least intrusive, minimally aversive (LIMA)-based strategies.
What to Expect From a Veterinary Behaviorist Consultation
A particularly thorough medical and behavior history is the first prerequisite for any veterinary behaviorist consultation, with the behavior history being the longest and most detailed part of the intake form. When did the problematic behavior first start, how often does it happen, and how has it changed?
The behaviorist also needs to know what interventions have been tried and how the dog responded to those treatments. The intake form will also ask the owner, “What are your goals for your dog? What outcome do you hope for?”
If the problematic behavior is unlikely to be observed in a veterinary office setting, the owner will be asked to try to capture video of the dog while he’s displaying the troubling behavior. Video can often provide the most valuable clues to the causes or significant contributors to the dog’s behavior.
After reviewing all of the above, the veterinary behaviorist will then meet with the dog and owner in order to observe the dog’s behavior first hand (or at least via a video conference).
At the end of the first visit, the client is usually given some management strategies that can be implemented right away – especially if the dog’s behavior has the potential for endangering anyone.
Afterward, the veterinary behaviorist will prepare a comprehensive treatment plan for the dog’s owner, which is typically reviewed and discussed in a subsequent appointment. The plan may include a request for medical tests (or further medical tests) in order to diagnose or rule out medical contributors to the problematic behavior. Usually, it will also include recommendations for the owner to undertake behavior modification exercises under the guidance of a training professional working with or recommended by the veterinary behaviorist.
The treatment plan may also recommend the use of supportive therapies such as supplements, nutritional therapy, and/or prescription medications (when appropriate).
Because there are few veterinary behaviorists, it’s impossible for many dog owners to book an in-person consultation with one. That’s why most of these professionals also offer phone or video consultations with their clients’ veterinarians. Instead of seeing the dog and owner, they will review the veterinarian’s report of the dog’s issues and directly communicate with the dog’s veterinarian to offer suggestions for further medical testing, medication, and behavioral interventions.
HOW TO BECOME A VETERINARY BEHAVIORIST
Veterinary behaviorists are veterinarians who have achieved board certification in the specialty of veterinary behavior. Certification takes a minimum of three years of study and training after a candidate has obtained a veterinary graduate degree. The certifying board for this specialty is the American College of Veterinary Behaviorists (ACVB); certificants, who are known as Diplomates, may use the initials DACVB along with DVM after their names.
To gain board certification, candidates must complete at least one year of internship or primary care practice. They must also undertake additional behavior-specific training, which includes at least three years of case supervision by an established DACVB. They must also conduct original behavior research that earns publication in a peer-reviewed journal, author three formal case reports that are approved by a review committee of Diplomates, and pass a rigorous two-day board examination administered by the ACVB.
There are only about 95 DACVBs located throughout the world (though other countries also certify veterinary behaviorists).
Some veterinary behaviorists have a solo practice, where they provide clients with support and referrals to other training or medical professionals as necessary. Others work in group practices, where other staff veterinarians can provide any diagnostic tests that the veterinary behaviorist recommends and staff trainers will work with the client and the client’s dog on behavior modification exercises.
Sample Case History
We asked a veterinary behaviorist to describe a typical case to illustrate how these professionals draw on their medical and behavioral expertise differently than their vet or trainer peers. Chris Pachel, DVM, DACVB, CABC, owner of the Animal Behavior Clinic in Portland, Oregon, accommodated us with a description of one of his veterinarian-to-veterinarian consultations.
The patient was a 3-year-old, intact male Labrador who had perpetrated a number of troubling episodes of what was described as unpredictable and unprovoked aggression in his home. His humans were highly experienced dog owners who were active in dog sports and had other dogs in the home, including additional dogs who would sometimes stay with them in a casual boarding scenario.
While the patient was usually a social butterfly with an affable temperament, the owners described a number of incidents where he had suddenly behaved aggressively. Fortunately, they had three of these incidents captured on video, thanks to their home security system.
One incident, where the patient became aggressive with his male owner, occurred in the backyard of the home when other dogs were present. In another incident, the dog aggressed toward that man’s mother when she moved a chair that was three or four feet from the dog. In the third incident captured on video, the patient aggressed toward a visiting dog.
Since the patient was perfectly social and appropriate in between these incidents – even in situations that were identical to the conditions in which he showed aggression – the owners brought the dog to their vet. About six months prior to the first aggressive incident, the dog had slipped and fallen with his front legs splayed out in an unnatural position. His owners were concerned that he might be experiencing pain that caused him to lash out at others.
On physical exam, their vet did find some pain and prescribed pain medication. The dog’s pain went away, but the troubling behavior did not. So, with the clients’ approval, the veterinarian scheduled a consultation with Dr. Pachel.
“It’s always necessary to have someone provide a thorough physical examination, but it doesn’t have to be me,” Dr. Pachel explains. In this case, he discussed the results of the primary care veterinarian’s physical exam, neurologic exam, and notes regarding the dog’s response to pain medication; he also read the behavior history and viewed the owner’s video clips.
From early on, Dr. Pachel suspected a medical cause for the aggression. “What stood out to me was the inconsistent relationship between the antecedents (things that happened around the dog prior to the aggression) and the behavior,” Dr. Pachel says.
“Seeing the variability and expression of those aggressive behaviors, and understanding that the dog has been in identical situations hundreds of times without eliciting any aggression – the most notable thing about the incidents were how inconsistent they were. That increased my level of suspicion that something internal, not external, was driving the incidents. The inconsistency also made me think about potential causes that have a waxing and waning, variable expression, such as hormonal issues or endocrine- related disorders.”
Dr. Pachel first suggested that the dog’s vet run a comprehensive thyroid profile (laboratory test). Dogs whose bodies produce too much or too little thyroid often experience changes in behavior and coping skills. However, the test results were normal.
Next, he considered endocrine conditions that could have an intermittent influence, impacting the dog’s ability to respond to mild provocations and stress. He suggested testing the dog for Addison’s disease – which may have appeared to the dog’s primary care vet as a stretch. “The dog had never had an Addisonian crisis (collapse, lethargy, dehydration), his electrolytes were normal – there were none of the hints in his bloodwork that would make you want to run an ACTH stim test (a test that demonstrates the capacity of the dog’s adrenal glands to produce cortisol),” describes Dr. Pachel. “It was the waxing and waning nature of the aberrant behavior and lack of response to other treatments that led me in that direction.”
While he may have thought the test was a shot in the dark, when the results came back, the dog’s primary care vet was happy to report that the picture was now clear: The dog had Addison’s disease, a deficiency of the hormones that regulate electrolytes, blood pressure, hydration, metabolism, and … stress responses! Addison’s patients require lifelong supplementation of those hormones, but thankfully, with treatment, the dog’s troubling behaviors stopped.
Is it just marketing?
It bears repeating: Anyone can call themselves a behaviorist. The term doesn’t guarantee that they are educated or experienced with complex behavior problems. When hiring a dog trainer, we recommend you choose a behavior professional who is certified by and/or a member of one of the organizations we list here: whole-dog-journal.com/training/find-the-best-trainer-for-you-and-your-dog.
Any ethical behavior professional will explore your dog’s behavior with you, help with behavior modification if they can, and refer you to a veterinary behaviorist if they realize your dog’s issues are beyond their experience and capabilities, or if their efforts to help are not successful.

Household Cleaner Puts Puppies at Risk, a Veterinary Toxicologist Says
https://www.inverse.com/science/household-cleaners-pets-safety-toxicity
Many cleaning products contain chemicals that, in large enough amounts, can be toxic to animals.
BYELANA SPIVACK MARCH 9, 2024 FROM INVERSE.COM
Cleaning products are crucial to keeping our homes clean and fresh. But are they safe for the furry creatures that live with us? Pets like cats and dogs stick their noses in so many things, not all of which are good for them. With that in mind, here’s how to ensure your cleaning routine is safe for your non-human best friend.
IT’S ALL ABOUT CONCENTRATION
Many cleaning products contain chemicals that, in large enough amounts, can be toxic to humans and animals. Senior veterinary toxicologist Ahna Brutlag at the Pet Poison Helpline and member of the American Board of Veterinary Toxicology, says bleach, ammonium, phosphoric acid, hydrogen peroxide, sodium hydroxide, and any type of phenol all appear in common household cleaners. When applied to the eyes or skin, like the exposed paw pads, they can irritate and even burn your furry friend.
But there is some good news: The concentration of these products matters, Brutlag says. Multipurpose surface and glass cleaners, for example, “have a pretty wide margin of safety,” she tells Inverse. What’s most crucial is using these products according to their directions. For example, if a spray directs you to rinse a surface with water after applying, then you certainly should.
Brutlag also suggests keeping pets away from freshly spritzed areas. A rule of thumb is that the area is safe again once you can no longer smell it. At that point, the spray has set and evaporated into the ether. Opening a window or turning on a ventilator while you’re cleaning can help to circulate fresh air for you and your pets and get rid of the smell faster.
NON-MAMMALS NEED PROTECTION, TOO
Opting for homemade cleaners made from vinegar, baking soda, and lemon isn’t necessarily safer, either. Vinegar may seem like a more wholesome option, but it will still sting your cat’s tongue if they walk through some and then groom themselves.
Brutlag calls out exotic pets. Birds are vulnerable to inhaling airborne particles that aerosols and spray bottles produce, so removing them from a room when using these chemicals is imperative. Amphibians can absorb compounds through their skin, so ensuring they’re safely locked away in their enclosures is a must. Once a cleaner’s scent disappears, feel free to uncover their tank again.
“PREVENTION, PREVENTION, AND PREVENTION”
More potent, corrosive cleaners like oven, drain, and toilet cleaners and rust removers, “have the potential to be significantly more harmful for people and pets.” These more caustic ingredients come in higher concentrations, so these products are much less diluted. “An ingredient is safe or dangerous based on the concentration,” she says.
These products also have a significantly higher or lower pH balance, which measures how acid or alkaline a substance is on a scale of 0 to 14. Water, for example, is completely neutral at 7. Bleach, oven cleaner, and drain cleaner come in at 13 and 14, making them extremely basic. These extremes make them such effective cleansers, but if you’re still concerned about their potency, you can dilute them further.
Dogs, especially puppies, are at high risk for poisoning because of their penchant for eating foreign objects. The form a cleaner comes in may also make it more dangerous to animals. According to David Dorman, professor of toxicology at North Carolina State University’s College of Veterinary Medicine, bite-sized dish and washing machine pods are of particular risk to dogs, who love putting things in their mouth. He urges pet owners not to discount any substance as a potential harm. This isn’t to say you should stop buying them, but rather that you should use and store them carefully.
Another aspect of cleaning and pet safety comes from how well-prepared you are. Dorman has three safety rules: “Prevention, prevention, and prevention,” he tells Inverse. Properly storing cleaning agents out of reach can save you and your pet a world of suffering. If that fails, then having a poison control number on the fridge means less vital time wasted looking up information.
If your pet walks through a puddle of cleaner or spills some on their coat, their skin or eyes may burn. You may notice your pet pawing at their eyes or chewing on a body part more than usual. In some cases, the strongest corrosives can even burn your pet’s tongue. Dorman suggests doing your best to wash the exposed area off with running water, though he acknowledges not every pet, especially those in discomfort, will be amenable to that.
Household cleaners are safe to keep around your pets as long as you’re mindful of where you keep them and how you use them. Provided you do that, cleaning around your pets should be a stress-free chore.

Service Dogs Lead to Fewer Seizures in Resistant Epilepsy
Thursday, March 14, 2024 Medscape Medical News by Eve Bender March 12, 2024
Working with medically trained service dogs is associated with a 31% reduction in seizures compared with usual care in treatment-resistant epilepsy, a new study showed.
Investigators speculate that the dogs may ease participants’ stress, leading to a decrease in seizure frequency, although they note this relationship warrants more study.
“Despite the development of numerous antiseizure medications over the past 15 years, up to 30% of people with epilepsy experience persistent seizures,” study author Valérie van Hezik-Wester, MSc, of Erasmus University Rotterdam in Rotterdam, the Netherlands, said in a press release.
The unpredictable nature of seizures is one of the most disabling aspects of epilepsy, Hezik-Wester added. Seizure dogs are trained to recognize seizures and respond when they occur.
“The tasks that these dogs perform along with their companionship may reduce seizure-related anxiety, also potentially reducing seizures caused by stress, the most common trigger for seizures,” she said.
The findings were published online on February 28 in Neurology.
Improve Quality of Life
The study included 25 individuals with medically refractory epilepsy who had an average of two or more seizures per week, with seizure characteristics associated with a high risk for injuries or dysfunction. They also had to be able to care for a service dog.
All were observed under usual care, which included antiseizure medications, neurostimulation devices, and other supportive therapies. Participants could then choose to work with a service dog that had completed socialization and obedience training or be assigned a puppy they would train at home.
The median follow-up was 19 months with usual care and 12 months with the intervention. Participants recorded seizure activity in diaries and completed surveys on seizure severity, quality of life, and well-being every 3 months. Daily seizure counts were converted to obtain cumulative seizure frequencies over 28-day periods.
Of the 25 original participants, six discontinued trial participation before the end of follow-up, four of whom left the study due to difficulty with dog care and training.
Participants receiving usual care reported an average of 115 seizures per 28-day period, while those with trained service dogs recorded 73 seizures in the same period, or a 37% difference between groups.
Researchers found that participants had an average of 31% fewer seizures during the past 3 months when they had seizure dogs, with seven participants achieving a 50%-100% reduction in seizures.
The number of seizure-free days increased from an average of 11 days per 28-day period before receiving a service dog to 15 days after working with a dog.
Scores on the EQ-5D-5L, which measures perceived health problems, decreased on average by 2.5% per consecutive 28-day period with the intervention, reflecting an increase in generic health-related quality of life (0.975; 95% CI, 0.954-0.997).
“These findings show that seizure dogs can help people with epilepsy,” said van Hezik-Wester. “However, we also found that this partnership with seizure dogs might not be the right fit for everyone, as some people discontinued their participation in this program. More research is needed to better understand which people can benefit from working with seizure dogs.”
Enhanced Quality of Life
In an accompanying editorial, Amir Mbonde, MB, and Amy Crepeau, MD, of Mayo Clinic in Phoenix, Arizona, noted the findings add to a growing body of work on the effectiveness of service dogs in reducing seizure frequency.
“In addition to improved seizure control, the EPISODE study demonstrated the benefit of seizure dogs in enhancing the quality of life for patients, a crucial component of comprehensive epilepsy care,” they wrote.
In prior studies, seizure dogs have identified an odor that a person emits before a seizure in up to 97% of people, they noted, adding that this ability “offers immense clinical benefits to people with epilepsy, enhancing their independence, social engagement, employment opportunities, self-confidence, and thus quality of life.”
Study limitations include its small sample size and high attrition rate.
The study was funded by the Netherlands Organization for Health Research and Development and Innovatiefonds Zorgverzekeraars. Smith and Jones reported no relevant financial relationships. The authors reported no disclosures.

Novel cancer vaccine offers new hope for dogs — and those who love them
A Yale researcher developed a vaccine that can slow or halt certain cancers in dogs. And it could be used to treat humans in the future.
By Mallory Locklear march 5, 2024
During a sunny morning on Florida’s Gulf Coast last month, an 11-year-old golden retriever named Hunter bounded through a pine grove. Snatching his favorite toy, a well-chewed tennis ball attached to a short rope, he rolled through the tall grass, with an energy that seemed inexhaustible. A passerby might not have even noticed that this playful golden has only three legs.
For Deana Hudgins, the dog’s owner, it seems almost unthinkable that two years ago Hunter was diagnosed with osteosarcoma, a form of bone cancer that kills upwards of 65% of the dogs it afflicts within 12 months, in his left front leg.
For many years Hunter worked alongside his owner as a search-and-rescue dog, helping find victims of building collapses and other disasters. He no longer performs those duties, but does still help Hudgins train other dogs. The energetic golden can also run, fetch, and catch as well as ever.
And two years since his initial diagnosis, Hunter has no signs of cancer. The dog’s life-saving treatment incorporated typical approaches, including amputation of the left leg and chemotherapy. But Hunter also received a novel therapy — a cancer vaccine developed by Yale’s Mark Mamula.
If we can provide some benefit, some relief — a pain-free life — that is the best outcome that we could ever have.”
The treatment, a form of immunotherapy that is currently under review by the U.S. Department of Agriculture (USDA), which regulates animal treatments, has been subject to multiple clinical trials over the past eight years. And the results are promising; for hundreds of dogs, including Hunter, the vaccine has proved effective.
Mamula, a professor of medicine (rheumatology) at Yale School of Medicine, believes the vaccine offers a badly needed weapon in the fight against canine cancer.
“Dogs, just like humans, get cancer spontaneously; they grow and metastasize and mutate, just like human cancers do,” said Mamula. “My own dog died of an inoperable cancer about 11 years ago. Dogs just like humans suffer greatly from their cancers.
“If we can provide some benefit, some relief — a pain-free life — that is the best outcome that we could ever have.”
Even as recently as a decade ago, Mamula didn’t anticipate that he would one day develop a cancer vaccine for dogs. A rheumatology researcher, he studies autoimmune diseases like lupus and Type 1 diabetes and how the body gives rise to them.
But that work eventually led him to cancer research as well.
Autoimmune diseases, Mamula says, are characterized by the immune system attacking the body’s own tissues; in the case of Type 1 diabetes, the immune system targets cells in the pancreas.
Then several years ago, using what they knew about autoimmunity, Mamula and his research team developed a potential cancer treatment that they say initiates a targeted immune response against tumors.
“In many ways tumors are like the targets of autoimmune diseases,” he said. “Cancer cells are your own tissue and are attacked by the immune system. The difference is we want the immune system to attack a tumor.”
It was a chance meeting with a veterinary oncologist soon thereafter that made Mamula think that this novel treatment might work well in dogs.
Targeting tumors
There are about 90 million dogs, living in 65 million households, in the United States alone. Around one in four dogs will get cancer. Among dogs 10 years or older, that ratio jumps to around one in two.
Yet the therapies used to treat these cancers remain fairly antiquated, Mamula says.
“There have been very few new canine cancer treatments developed in decades — it’s a field that is begging for improvement,” he said.
In 2015, Mamula met a veterinary oncologist named Gerry Post. During his 35-year career Post has treated cancer in snakes, turtles, and zoo animals. But most of his patients are dogs and cats.
Through conversations with Post, Mamula realized that it wouldn’t be difficult to make the leap from human to dog cancers. Together they would launch an early-phase study into Mamula’s dog cancer vaccine.
“Dog and human cancers are quite similar in a number of ways,” said Post, chief medical officer of One Health Company, a canine cancer treatment group, and an adjunct professor of comparative medicine at Yale School of Medicine. “Whether it’s how the cancers appear under the microscope, how the cancers behave, respond to chemotherapy, develop resistance, and metastasize.”
After talking with a veterinary oncologist, Mamula realized that it wouldn’t be difficult to make the leap from addressing human cancers to dog cancers.
Even the types of cancers that afflict dogs and humans are similar. Like humans, dogs can get melanoma, breast cancer, colon cancer, and osteosarcoma, among others.
When it comes to curing these diseases, these similarities bring an important benefit: understanding cancer in one species will help scientists understand cancer in the other. And treatments that work well for one may actually work well for both.
Several types of cancers in both humans and dogs have been found to overexpress proteins known as epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER2). These include colorectal cancer, breast cancer, and osteosarcoma. One type of treatment currently given to human patients with these cancers involves monoclonal antibodies, proteins that can bind to and affect the function of EGFR and/or HER2. However, patients can develop a resistance to them and their effects wane over time.
For their treatment, Mamula and his team wanted to take a different approach.
Monoclonal antibody treatments are produced from one immune cell and bind to one part of the EGFR/HER2 molecules, but Mamula and his team wanted to induce a polyclonal response.
Doing so, he says, would create antibodies from multiple immune cells, rather than just one, which could bind to multiple parts of the EGFR/HER2 molecules instead of a single area. This would, in theory, reduce the likelihood of developing resistance.
The research team, led by Hester Doyle and Renelle Gee, who are both members of Mamula’s Yale lab, with assistance from the New Haven-based biotechnology company L2 Diagnostics, LLC, tested many different candidates in order to find just the right compound. They eventually found one.
After first testing it in mice, and finding promising results, they initiated their first clinical trial in dogs in 2016.
‘I was willing to try whatever I could’
Deana Hudgins knew there was something special about Hunter before she brought him home as an 8-week-old puppy, back in 2012, and began training him to be her next search-and-rescue partner.
The smallest of 18 puppies from two litters, Hunter wasn’t the obvious choice when she began looking for a partner.
“He was the runt,” said Hudgins, who has been training search-and-rescue dogs since 2001 and now runs her own company, the Center for Forensic Training and Education, which provides canine training in Ohio and Florida. “But in his case, it made him a little scrappy. He was small but very confident and very brave.
“When all of the other puppies were sleeping at the end of the day, he was still running around, climbing all of the toys, retrieving things. We need confident puppies, and that’s what he possessed.”
By the time he was a year old, Hunter began aiding searches at sites across the United States, working with local law enforcement and the Federal Emergency Management Agency (FEMA), following natural disasters. His first search, in 2014, was at the site of a mudslide in Oso, Washington that killed 43 people. In his final FEMA search, he helped search for victims of the devastating condominium collapse in the Miami suburb of Surfside, Florida, in June 2021. Hunter was involved in hundreds of searches in the years between.
In 2022, Hunter was still very active — and had just earned another service certification — when Hudgins noticed that he seemed uncharacteristically sore following a five-day training class.
“I’ve always been very proactive with my dogs because I spend every day with them, and so I notice very little things,” she said. “And he’s not a dog to limp.”
A veterinarian assumed that Hunter had strained something, suggesting anti-inflammatories, but Hudgins insisted on an x-ray. The test revealed the osteosarcoma in Hunter’s leg.
After doing a lot of research, and consulting with different veterinary groups about what steps to take, Hudgins decided that amputation offered the best chance for Hunter’s survival, along with chemotherapy.
But during that research, Hudgins had also come across Mamula’s vaccine trial. So she reached out to a colleague, James Hatch, a former Navy SEAL who trained dogs in the military and whose nonprofit supports service dogs. Hudgins knew that Hatch also happened to be at Yale, where he is a student in the Eli Whitney Students Program.
“I was willing to try whatever I could to keep [Hunter] around as long as possible,” said Hudgins. “We ask a lot of our working dogs. They work in environments that are very dangerous and often deadly. And my promise to all of them is I will do whatever I have to do to give them the best, healthiest, longest life possible. Dogs don’t survive this disease so there was no downside to me for trying the vaccine.”
Hatch connected her with Mamula, and soon Hunter was part of the clinical trial. He received his first vaccine dose ahead of his amputation surgery, his second before initiating chemotherapy, and a booster last summer.
Twenty-two months since his cancer diagnosis, Hunter is now considered a long-term osteosarcoma survivor and Hudgins says he’s thriving.
“He adjusted very well to his front limb amputation,” she said. “He continues to run around the yard. He swims in the pool. He comes with me to training and chases the other dogs around the yard.”
During a recent morning in Florida, Hunter drifted toward a nearby pond while playing outside. Hudgins, knowing the potential risks of straying too close to a pond in Florida (“There are alligators everywhere.”), quickly called him back. Hunter immediately returned to her.
“From a very young age, Hunter wanted to learn the rules of the game,” she said. “He was eager to go to work every day. I am very, very lucky to have been able to be his partner for 10 years. Hunter is one of those once-in-a-lifetime dogs.”
‘A whole new toolbox’
Hunter’s positive response to the treatment is one many other dogs have experienced as well.
To date, more than 300 dogs have been treated with the vaccine during a series of clinical trials, which are still ongoing at 10 sites in the U.S. and Canada. The findings, which have been published in a peer-reviewed study, have shown that the treatment creates antibodies that are able to home in on and bind to tumors, and then interfere with the signaling pathways responsible for tumor growth.
According to the research team, the vaccine increases the 12-month survival rates of dogs with certain cancers from about 35% to 60%. For many of the dogs, the treatment also shrinks tumors.
While future studies will determine if the vaccine can reduce the incidence of cancer in healthy dogs, the treatment for now remains a therapeutic treatment option after a cancer diagnosis has been made.
Witnessing the happiness that successful therapies provide to families with dogs is incredibly rewarding.
But even this represents something more than just “a new tool” in the fight against canine cancer, Post says. It’s a whole new toolbox.
“And in veterinary oncology, our toolbox is much smaller than that of human oncology,” he said. “This vaccine is truly revolutionary. I couldn’t be more excited to be a veterinary oncologist.”
Mamula has created a company, called TheraJan, which aims to eventually produce the vaccine. Last year, the company (whose name is inspired, in part, by the late Yale immunologist Charles Janeway, who was Mamula’s mentor) won a Faculty Innovation Award from Yale Ventures, a university initiative that supports innovation and entrepreneurship on campus and beyond.
While launching clinical tests of the vaccine’s effectiveness in humans may be a logical future step, for now Mamula is focused on getting USDA approval of the vaccine for dogs and distributed for wider use.
No matter where it goes, it’s a project close to his heart.
“I get many emails from grateful dog owners who had been told that their pets had weeks or months to live but who are now two or three years past their cancer diagnosis,” he said. “It’s a program that’s not only valuable to me as a dog lover. Witnessing the happiness that successful therapies provide to families with dogs is incredibly rewarding.”
And once the vaccine becomes available for public use, he says, for working dogs like Hunter it will always be free of charge.

Ear Mites in Dogs
Not all messy ear conditions are due to mites. Learn to recognize the signs of ear mites in dogs and get appropriate treatment for your dog’s ear mite infection.
By Dr. Jennifer Bailey, DVM – Published: February 27, 2024
Are itchy, stinky ears interfering with your dog’s daily dose of fun? A quick internet search might lead you to ear mites in dogs as the culprit. You can try administering an ear mite medication in your dog’s ears to alleviate his discomfort. But before you reach for that over-the-counter ear mite medication, you should know more about ear mites in dogs, and learn when to call in a professional (in other words, your dog’s veterinarian!).
Otodectes cynotis is an ear mite that infects the ear canals of dogs, cats, rabbits, and ferrets. Although this species of ear mite prefers these three species of mammals, any mammalian species will satisfy its needs for survival. It survives by ingesting the dead skin cells and ceruminous exudate (ear wax) that line the ear canals.
Symptoms of ear mites in dogs
Ear mites in dogs cause an inflammatory reaction in their ear canals. This is what causes your dog to scratch at his ears and shake his head. The ceruminous glands that line your dog’s ear canals ramp up production of even more ear wax to drive out the ear mites. That smelly, dark brown, crumbly discharge in your dog’s ears is a combination of ear wax, ear mites, and their excrement. It often resembles the color and texture of coffee grounds.
Dogs who have ear mites will often develop a secondary bacterial and/or yeast infection in their ears. This can change the color and texture of the ear discharge from crumbly brown to creamy yellow or green. Sometimes the discharge may be mixed with blood if your dog scratches his ears so hard that they bleed.
If it becomes too crowded inside your dog’s ears, then some of the mites will leave the ear canals to find more spacious living quarters. Ear mites can live on the skin surface outside of your dog’s ears, snacking on skin oils and dead skin cells. They can be found crawling on the skin around the ears and on the neck and face. When your dog curls up in a ball to sleep, the mites can crawl out of the ears onto the skin of the rear end or tail. Mites will cause itchiness wherever they reside, so dogs with ear mites may scratch and develop skin redness and bald spots in areas besides their ears.
The only way to accurately diagnose an ear mite infestation is to examine a sample of your dog’s ear discharge under a microscope. The average length of an ear mite is only three-tenths of a millimeter. While this is too small to be seen by most people’s unaided eyes, ear mites can be easily spotted under a low-power microscope lens.
Treatment for ear mites in dogs
There are several treatments available to rid your dog of ear mites. But the only dogs who should receive treatment for ear mites are ones who have been diagnosed with ear mites or who live in a home with a pet who has been diagnosed with ear mites. Ear infections caused by bacteria, yeast, or a combination of bacteria and yeast can look similar to ear mite infestations.
It is important to know what you are treating before you treat. Using the incorrect treatment can worsen the underlying problem, cause more pain for your dog, and may lead to hearing loss or deafness. If your dog is scratching at his ears, shaking his head, and having discharge from his ears, have your dog examined by a veterinarian as soon as possible to determine the best course of treatment.
How do dogs get ear mites?
Ear mites spend their entire life cycle on one or more host animals. Ear mites can live for a few days in the environment but cannot survive without being on a host animal.
Ear mites spread by crawling between animals. They cannot hop or jump. To become infested with ear mites, a dog must have direct contact either with another animal who has ear mites or the gunk that recently came out of an infected animal’s ears.
How to prevent ear mites in dogs
Regularly use a flea or heartworm preventative that contains an ingredient shown to be effective against ear mites, such as Revolution, Advantage Multi, Interceptor, Nexgard, Bravecto, or Simparica.
If there are cats in the home who venture outside, regularly use a flea preventative on those cats that contains an ingredient shown to be effective against ear mites, such as Revolution, Advantage Multi, or Bravecto.
If there are ferrets in the home who venture outside on a harness and leash or rabbits in the home who spend time outdoors in a hutch or pen, talk to your veterinarian about applying Revolution monthly to these pets. This is an off-label use of Revolution in these species and must be prescribed and dosed correctly by your veterinarian.

What To Do If Your Dog Or Cat Is Stung By A Bee
Exploring new places with your pets often includes spending time outdoors. And being out in nature means you’re more likely to run into stinging insects. In this post you’ll learn what to do if your dog or cat is stung by a bee.
No one likes being stung. At the very least, it’s going to be uncomfortable. And because dogs and cats can have allergic reactions similar to humans, being stung by a bee can be a serious concern. Fortunately, there are some steps that you can take to help keep the bees at bay.
Avoid Confrontations
The safest strategy is to avoid a tangle with the wrong insect … though convincing your pets to cooperate can be difficult! So, it’s important to take some precautions to help your dog or cat stay away from bees.
Start in your yard by growing plants like chrysanthemums, lemongrass, or primrose, which don’t attract bees. When you and your pet are outside, burn citronella candles and don’t leave food outdoors. And make sure you’ve trained your dog to “leave it” whenever he’s tempted to put his nose where it doesn’t belong.
Your Dog Or Cat Has Stung By A Bee – Now What?!
Still, even if you take all the precautions, accidents happen. Pets can be stung on the face, inside the mouth, on their paws, or on other parts of their bodies if they snap at, sit on, or step on a bee. So it’s best to be prepared!
How To Tell If Your Pet Has Been Stung
If you don’t actually see your dog cat get stung by a bee you’ll need to look for other clues of the encounter. Check for swelling, pawing at the face, or obsessive licking. These are signs that your best friend has met business end of a stinger.
If you notice these symptoms, you’ll need to watch your pet carefully for the next few hours. Some animals, like some people, are highly sensitive to insect toxin. In those cases, your pet could experience Anaphylactic Shock, a severe allergic reaction which can cause the circulatory system to shut down.
Signs Of A Serious Allergic Reaction To A Bee Sting
If you notice any of the following symptoms, which usually occur within an hour of the sting, DO NOT DELAY in getting veterinary care:
1. Severe and profuse swelling (i.e. entire face as opposed to just the lip)
2. Difficulty breathing or increased respiratory effort possibly due to throat swelling
3. Very pale or blue-tinged mucous membranes (inner lips and gums)
4. Rapid and/or irregular pulse
5. Prolonged Capillary Refill Time (Refer to “Checking Your Pet’s Vital Signs,” but if gums are pale, or if it takes longer than 2 seconds for the color to return to the gum when pressed with your finger, your pet needs immediate medical care.)
Treating Your Pet’s Bee Sting
Even if your pet doesn’t appear to be having a severe reaction, the sting might still be painful. Keep a close on him while you gather the following items:
- Cold Pack
- Baking Soda or Meat Tenderizer Containing Papain
- Epi-pen, if your pet has had previous encounters with bees and is known to be allergic
- Water
- Syringe, Eye Dropper, or Spray Bottle
- Diphenhydramine/Benadryl®
(Note: The product you purchase should contain diphenhydramine as the only active ingredient. Some products contain additional ingredients such as xylitol (in Benadryl no-sugar syrups) or decongestants such as pseudoepinephrine. Both xylitol and pseudoepinephrine are potentially lethal to dogs. So check with your vet, and only consider giving Benadryl if it contains diphenhydramine and nothing else.)
Depending on where your dog or cat has been stung by bee, there are some steps you can take to help speed their recovery.
IF THE STING IS INSIDE THE MOUTH:
— Offer your pet an ice cube or small amount of ice water to minimize swelling
— Seek immediate advice from your veterinarian, as the mucous membranes of the mouth will more quickly absorb the insect toxin. Should your pet’s tongue swell, giving rescue breathing might be impossible, and a veterinarian will be best equipped to help.
IF THE STING IS ELSEWHERE ON THE BODY:
The stinger might be concealed in your pet’s fur, or it could already have been pawed away. But if you can see it, flick it away with a credit card, popsicle stick, or your finger nail. Do not pull the stinger with your fingers or tweezers as you can puncture the poison sac, allowing more toxin to enter your pet’s body.
If you have an epi-pen prescribed specifically for your pet due to previous allergic reactions, read and follow the attached instructions. Follow up immediately with your veterinarian as anaphylaxis can occur.
If you can locate the sting site, dab it with a paste made from 1 Tablespoon baking soda or meat tenderizer mixed with a drop of water. (Meat tenderizer and baking soda are both alkaline and work to counteract the acidity of the toxin. Also, the papain in tenderizers breaks down the protein in the toxin.)
Administer diphenhydramine (Benadryl® antihistamine). While this medication is generally considered safe for cats and dogs, consult with your veterinarian to determine the proper dosage. Also discuss any other medications your pet is taking and any pre-existing medical conditions. Diphenhydramine will help relieve mild allergic reactions and make your pet sleepy, allowing him to relax and prevent him from scratching the sting site. If swelling persists for more than 6-8 hours, consult your veterinarian for further treatment.
Apply a cold pack to reduce swelling, but remove every few minutes to avoid frostbite. Placing the cold pack in a damp washcloth will help keep your pet’s skin from getting too cold.
Homeopathic Tip: Apis Meliffica, also known as Honey Bee, can aid the body in reducing the burning or stinging pain.
Preparations For Traveling With Pets
Of course, bee stings don’t always happen when you’re at home. So make sure the items you’ll need to treat a bee sting are in the first aid kit in your car and in your hiking backpack.
Also, if your pet is too large to fit into your backpack, consider getting an emergency sling (affiliate link) that would allow you to carry him back to your car.
Being prepared allows you to give your pet the attention he needs quickly. And the sooner he’s better, the sooner you can both get back to having fun.
