Methicillin-resistant bacteria occur in humans and animals and don’t respond to the usual spectrum of antibiotics, writes veterinarian Mary Ann Crawford. The human culprit, methicillin-resistant Staphylococcus aureus, only occurs in pets as the result of reverse zoonosis, so pets with this bacteria will trigger an investigation into the health of their human companions, Dr. Crawford points out. The methicillin-resistant bacteria of concern in animals is Staphylococcus pseudintermedius, and although it’s unusual, transmission to humans can occur, so gloves, hand-washing and hand sanitizer should be used to prevent transmission, Dr. Crawford notes. The Record (Hackensack, N.J.)

Q. My neighbor’s dog has a wound that is being treated with antibiotics but it is not healing. I have heard lots of information about the bacteria called MRSA being such a terrible thing. Could this be affecting my neighbor’s dog?

MRSA stands for methicillin resistant Staphylococcus aureus. Resistance means that a bacterial infection is not able to be treated effectively by the most commonly used antibiotics. MRSA is a type of bacteria that may affect people but can also be transmitted to animals. It is known as a “reverse zoonosis,” meaning a condition that would travel from a person to an animal, rather than the other way around. When animals have an infection cultured that reveals the MRSA bacteria, we want to question the owners about any infections the people may have in the household.

We do not mean to imply that animals don’t get resistant bacterial infections, because they do, although it is not common. The Staph bacteria affecting animals is called Staphylococcus pseudintermedius (SP), rather than Staphylococcus aureus (SA). There is a methicillin resistant form called MRSP. It is an easily transmissible bacteria from animal to animal, and gloves should be worn when treating any open wounds or known areas of infection. It would be very rare for a person to acquire an infection of MRSP, but anytime there is an open wound present either in an animal or person, the area should only be touched with gloves. Hands should also be cleaned with soap and water after being in contact with the dog or person, followed by an alcohol based disinfectant such as Purell.

We identify bacterial infections by obtaining a sample of the infected area and sending it to a laboratory for identification (culturing). The laboratory also provides us information about which antibiotics the bacteria are susceptible to. The laboratory informs us if the bacteria are a resistant strain such as MRSA or MRSP, and this helps guide our treatment recommendations for therapy. Since the wound has not been responding, your neighbor should consider returning to their veterinarian where they will likely consider culturing the infected area.

Pets are exposed to the same potentially harmful substances as the humans they live with, possibly to a greater extent because they are smaller and closer to the ground, according to this article. Simple changes can reduce pet — and human — exposure, including vacuuming frequently and keeping potentially harmful substances such as medications in a safe place. Emergency veterinarian MeiMei Welker discusses the harms of slug bait, rodenticide and marijuana poisoning, while veterinarian Marli Lintner explains the uniquely sensitive nature of birds to home toxins, such as fumes from nonstick pans, due to their respiratory systems. The Oregonian (Portland) (3/1)

We think that our indoor pets are safe from predators, cars and disease, but our homes may be exposing our pets – and ourselves – to risks of a different realm.

Everything from the mattresses we sleep on to the motes of dust on the shelves may contain flame retardants or other chemicals, says Laurel Standley, an environmental consultant and author of “#ToxinsTweet: 140 Easy Tips to Reduce Your Family’s Exposure to Environmental Toxins.”

Standley began studying the effects of household toxins in pets after she, her mother and sister all lost pet cats to cancer.

She grieved the losses but Standley, who earned a doctoral degree in chemical oceanography, also grew concerned about what made them sick in the first place.

She worries about the prevalence of chemical flame retardants known as polybrominated diphenyl ethers (PBDEs) found in many electronics, polyurethane foams, carpet padding, furniture, mattresses and other common household items.

“Each time we sit down on couches with foam cushions, dust particles fly out and fill our homes with dust containing flame retardant chemicals,” Standley says.

The products are being phased out after growing concern about their health effects. Last month, California Gov. Jerry Brown proposed new standards to reduce use of fire-retardant chemicals in furniture and baby products.

Some studies have associated hyperthyroidism in cats to the presence of PBDEs, including one published in February 2012 in the Journal of Toxicology and Environmental Health.

“Proving cause and effect is extremely difficult,” Standley says, “But that’s not an excuse to not protect our pets.”

Plastics also contain harmful chemicals, including bisphenol A and phthalates that have been associated with reproductive and other endocrine effects.

Some of these chemicals have been restricted from children’s products (such as the Multnomah County ban on sippy cups and baby bottles made with BPA).

“The same chemicals haven’t been regulated for dog or cat toys,” says Jennifer Coleman, outreach director at Oregon Environmental Council. “They could still have an impact on endocrine systems.”

Like infants, pets are also smaller than adults, metabolize more quickly and are closer to the ground. This makes them more vulnerable to harm from many of the products humans use, she says.

One way to reduce their exposure is by replacing plastic food bowls with those made from stainless steel, ceramic or glass instead, Standley suggests.

The fish in those food dishes can also be toxic; fish living in polluted streams can accumulate toxic substances in their systems, she says.

Even the plastic liner of the cans they come in may leach BPA.

Pigments and dyes are also likely to contain chemicals, so look for toys without a lot of color or bleaching, Coleman advises.

“My strategy with my own dog is to do the simple things that make the most sense to me,” she says.

She avoids vinyl and PVC plastic and opts instead for those made from rubber or fabric, such as tug ropes and stuffing-free toys. Even tennis balls can be toxic; the ones designed for dogs often contain lead.

Of course, some toxins will make your pet sick sooner rather than later.

At DoveLewis, veterinarians see some toxins more often than others. Metaldehyde slug bait ingestion can cause major muscle tremors that can be fatal, as well as liver problems, says staff veterinarian Dr. MeiMei Welker.

The emergency animal hospital also sees a fair number of dogs sick from marijuana ingestion, while rodenticide toxicity – suspected in the death of a prize-winning Samoyed recently– is a near-daily occurrence.

There are several kinds of rat bait, but the anticoagulant rodenticides are slower to act and allow more of a window of time to administer the antidote.

If your pet consumes poison of some sort, it’s best to bring the packaging to the veterinarian so he or she can treat it most effectively.

Other common toxins seen at DoveLewis include raisins and grapes; the sugar substitute Xylitol; Easter lilies; chocolate; ibuprofen and naproxen (Aleve); and acetaminophen.

The canary in the kitchen

Birds are uniquely sensitive to their environment; there’s a reason the phrase “canary in a coal mine” became so popular.

They’re very sensitive to aerosols, and their respiratory systems are very different than ours, says Dr. Marli Lintner of the Avian Medical Center.

Bird lungs are designed to breathe in very clean, thin air, so breathing in some toxic inhalants can kill them immediately or make them very sick.

“Any sort of fume that makes your nose tingle or your eyes water is bad news for the birds,” Lintner says.

Fumes from nonstick pans pose one of the biggest threats to our feathered friends.

Once the pans overheat – usually when the temperature reaches above 530 degrees Farenheit – a gas called polytetrafluoroethylene is released, says Dr. Deborah Sheaffer, staff veterinarian at the Audubon Society of Portland.

They can die very quickly, so if you see your bird panting or having trouble breathing, you should take it to the veterinarian immediately.

Lead poses another common avian household hazard. Paint, stained glass window frames, curtain weights, costume jewelry; foil from champagne bottles; and old bird cages can all be toxic.

“When people have pet birds, they really need to be cognizant of what’s around them,” Sheaffer says. “They’re curious and inquisitive and they like to chew on things.”

This may be a lot of information for you to chew on too. Just remember that making your home safer for your pets makes it safer for humans as well.

How to help reduce toxins in your home

Vacuum frequently, preferably with a cleaner fitted with a HEPA filter, even on tile or wood floors (the goal is to not sweep dust up from the floor).

• Eliminate carpet wherever possible; the less carpet you have, the easier it is to control dust.
• Use rugs made of natural fabrics, such as cotton, wool or jute.
• Vacuum your couch regularly.
• Dust with a simple damp rag. Dry dusting can stir dust back into the air.
• Replace plastic food dishes with those made from stainless steel, ceramic or glass instead.
• If you have birds, avoid using nonstick pans whenever possible.
• Don’t expose birds to smoke or household aerosol products such as harsh cleaners, perfumes, hairspray, etc.
• Keep pets off the countertops and secure medications and other toxins safely in cupboards.
• If you’re afraid your pet ingested something he shouldn’t have, call the Pet Poison Helpline at 800-213-6680 (consultations cost $39).
• Don’t try to make your pet vomit; in some cases it could make the situation worse.

More than 80% of pets over 8 years old have an illness their owners aren’t aware of, writes veterinarian Donna Solomon, who says it’s not because owners aren’t looking. Rather, pets are masters of deceit, deftly hiding symptoms or exhibiting only barely noticeable changes in behavior because that’s what their wild ancestors had to do to stay alive. Regular veterinary examinations are the best way to ensure covert illnesses may be detected in time for intervention. The Huffington Post/The Blog (3/11)

In a recent focus group study presented at the January 2013 North American Veterinary Conference, veterinarians were asked if they found it challenging to diagnose medical conditions in dogs and cats.  Fifty-seven percent of the veterinarians found it challenging to diagnose conditions in cats and 34 percent challenging in dogs. Now, imagine asking pet owners who have no medical training the same question. I’m confidant that the percentage of people finding it challenging to diagnose conditions in their dog or cat substantially higher.  In fact, many clients do not even recognize their pet is ill or in pain.  Did you know that over 80 percent of all pets over eight years of age have at least one unrecognized disease by their owners?

Why is it so difficult to recognize a sick pet? First, pets do not clearly articulate what is wrong with them. Wouldn’t it be wonderful if your cat told you the reason she is urinating in your bathroom sink is because she has a bladder infection?  Second, dogs and cats hide their illnesses for instinctual purposes. In the wild, pets that are ill and display overt signs of not feeling well will likely fall victim to predators.

To highlight the difficulties of recognizing an illness in your pet I would like to present you three recent medical cases I have seen at Animal Medical Center of Chicago.

Case 1: The case of the fighting brothers.

Last week I had the pleasure of examining two beautiful Somali cats for their annual physical examination. Historically, these 2-year-old cats were loving brothers. They played, groomed and slept curled around each other every night. Recently, however, the owners had noticed that the cats were fighting more and not sleeping together.  On physical examination of both cats each had severe stomatitis — which is a term reserved for severe inflammation of the gum tissue.  The gums were ulcerated and cherry red in color. I informed the clients that both of their cats needed immediate dental care, which would include a dental cleaning, probing, radiography and oral surgery to remove numerous problematic teeth. The owners were shocked that they did not notice any problems. The cats were eating well and showed no obvious dental pain like drooling, difficulties chewing or facial swelling. I told the clients that pet’s can be very secretive about their pain — it is an adaptive response to living in the wild. To temporarily reduce their pets’ discomforts, I sent the clients home with pain medication and antibiotics. We scheduled oral surgery for the following week. Two days later I called the client for an update and the pets were doing great. They were playful and positively interacting with each other again. As the client reported, “They are acting like kittens again.”

Case 2: The case of the stoic shelter dog.

Approximately two weeks ago a client rescued a really sweet, probably 2-year-old pit-bull, named Pilot, from a local shelter. Pilot had been sitting in a shelter cage for almost four weeks after being abandoned on the streets. The dog walked with a slight limp on his left hind limb. When he was standing still, I noticed that he would shift almost 75 percent his weight onto his right hind limb. A pelvic radiograph revealed multiple pelvic fractures. Although it was tragic that this pet was in a shelter cage for almost a month without any medical care, this benign neglect worked to his benefit. His immobility allowed the fractures to almost heal by itself.  Since the fracture was healing nicely on its own, I recommended to the owner to start anti-inflammatory and pain medications along with some nutra-pharmaceutical drugs to help with wound healing. I told her to continue to severely limit his activity and repeat pelvic radiographs in four weeks. Unfortunately (or maybe fortunately??) Pilot has an extremely high pain threshold that masked his true problems.  I believe the well-intentioned shelter workers did not perceive Pilot in discomfort and therefore, did not seek appropriate medical or surgical care.

Case 3: The case of the playful Labrador retriever.

Just the other day one of my clients brought in her playful 8-year-old Labrador retriever, named Bentley, for a yearly examination. When I entered the room Bentley was jumping up and down off our examination table looking for treats. I asked the owner routine questions like, ” Is Bentley eating well? Is he having normal stools?  Any signs of orthopedic discomfort, like difficulties going up and down stairs or stiffness after rising?” The owner told me that after daycare Bentley is exhausted and can barely walk. She told me that she thinks he is just tired and that’s it. During my physical examination, I discovered that Bentley was moderately painful when I palpated both hips and shoulders. I told her that her dog is most likely suffering from degenerative joint disease (arthritis) and not exhaustion. I recommended radiographs of the problematic joints. The owner had not perceived Bentley in pain or suffering from any musculoskeletal problem given her dog’s energetic personality but it was obvious from my examination that he was uncomfortable.

These three cases are perfect examples of pet’s hiding their illnesses or diseases from their owners. Every day clients bring their “apparently healthy pet” to see me for their yearly examination and I frequently discover a medical condition that the client did not recognize. It is not that my clients are not observant or loving, it is that a pet will do their best to hide a problem.

Given their secretive nature, if your pet’s behavior deviates from its normal routine, please take note of it. Maybe he/she is trying to discretely tell you something.  If he/she is sluggish, seeking more or less attention, or not eating with the same gusto as it normally does, this may be your only sign that something may be awry. Please contact your veterinarian for advice.

Be observant. Be your pet’s best advocate for good health care. Don’t let your pet keep secrets!

To maximize the length and quality of an aging cat’s life, veterinarian Julie Damron writes that owners should schedule semiannual veterinary exams and have regular lab work and routine dental care performed. Be sure vaccinations are current, feed a high-quality diet to provide essential nutrients and maintain a healthy weight, and keep cats indoors, Dr. Damron advises. Owners must remain vigilant because cats are good at concealing health issues, and subtle changes may be difficult for owners to detect, according to Dr. Damron. The Record (Stockton, Calif.) (tiered subscription model) (3/9)

It’s important to keep close watch on your feline during his or her golden years. Traditionally, cats are considered senior when they reach age 7. At this point in life, their bodies will change more rapidly and there can be several health issues of concern.

Make sure your feline has a veterinary exam every six months. This is important. Although your cat may appear healthy to you, there are subtle changes that can be occurring within his or her body. Cats are very good at hiding disease. Because they are smaller, it can be difficult to notice changes in weight.

Keep your cat’s vaccines current unless otherwise recommended by your veterinarian. Even indoor cats can be exposed to illness. Routine RCP vaccines, which protect from viral rhinotracheitis/herpes and calicivirus, should be given to help protect from respiratory infections as your feline ages. It is also important to keep your feline protected from rabies.

Have lab work done at least once a year. Felines are very prone to develop organ disease as they age, especially hyperthyroidism and kidney disease. Symptoms and physical exams can suggest maladies but these illnesses can only be diagnosed through blood and urine analysis. When a medical problem is identified in the earliest stages and treated promptly, it allows for the best outcome.

Provide a high-quality diet that is designed specifically for senior cats, given in the correct quantities. Feeding a premium pet store-quality diet makes a big difference in the longevity of your feline companion. The phrase “you are what you eat” applies to felines as well as people. A higher quality of nutrition is directly connected to longevity in cats. It is also just as important to control caloric intake in our companions as it is in people. Cats that are obese are at risk for diabetes, heart disease, joint problems, and other issues just like in people. If you have more than one cat, feed them individually, so that you can be more aware of how much each feline is eating.

Provide routine preventive dental care. Dental disease affects much more than the wellness of your cat’s mouth. Bacteria from infection of the mouth can be spread to other organs in the body, bathing them in pathogens. Pain and inflammation at the mouth can also lead to decreased appetite, causing a cascade of illness. Tartar on the teeth leads to inflammation along the gum line. Over time, the gum tissue will recede from the base of the teeth. Continued infection allows for loosening of the ligaments that hold the teeth in place. Eventually the teeth will fall out.

There is a lot that you can do to keep your feline’s mouth healthy. A high-quality dry food helps to reduce tartar development. Routine oral care in the form of brushing, treats and rinses can help to reduce plaque buildup. Dental cleanings can help to treat and limit the advancement of dental disease.

It is recommended that all cats are spayed or neutered, and this is especially important for older felines. Older females that are not spayed are more prone to infections in the uterus as well as mammary, ovarian and uterine disorders.

It is also best to keep felines mainly indoors, especially when older. When cats live outside, they are at risk of ingesting toxins, being attacked by other animals, being hit by a car, and other hardships.

Consistency with these steps in combination with love and attention will help to improve the quality and quantity of the years with your feline companions.

Parvovirus is a potentially deadly viral infection that afflicts dogs, and treatment requires intensive care, writes veterinarian Karen Dye. The animal must be isolated because the virus is highly contagious, and care involves delivering intravenous fluids, monitoring and adjusting electrolyte levels, and treating secondary infections, writes Dr. Dye. An appropriate vaccination protocol is the best way to prevent parvovirus, she notes. Cats cannot contract parvovirus from dogs, but they do acquire a similar virus, panleukopenia, that can be deadly and must be treated by a veterinarian. The Culpeper Star-Exponent (Va.)

Q:   My puppy was diagnosed with parvovirus.  Can I treat him from home?

A: Ideally, puppies with parvovirus should be treated as inpatients in the hospital.  Parvovirus infection is an acute systemic disease that requires prompt, intensive supportive care in the hospital to be most successful with treatment.

Signs include sudden onset of lethargy, bloody diarrhea, anorexia and vomiting.  Some puppies may collapse and die without any signs.  Dogs that are from kennels, animal shelters and pet stores are at greater risk.  Also puppies that are younger than four months of age are at higher risk of severe infection.   Concurrent diseases such as intestinal parasites or other viruses such as coronavirus may exacerbate the illness.  Crowding and poor sanitation increases risk of infection as well.

Virus can be detected in the stool at the onset of disease and for 2-4 days afterward with in-house laboratory testing.  Lymphopenia is very common (low lymphocyte counts) and leukocytosis is common during recovery (increased White Blood Cell count).

Treatment is aimed at supportive, symptomatic care.  Controlling vomiting is of essence.  Correcting dehydration and electrolyte abnormalities are important as well.  This is best done in the hospital with intravenous balanced fluid therapy.  We are able to monitor patients’ response if they are hospitalized.  These patients do need to be hospitalized in isolation due to the highly contagious nature of the virus.  Thorough disinfection is needed with a bleach solution to destroy canine parvovirus shed into the environment.  Food and water is withheld until vomiting is controlled; once puppies are recovering, they should be fed a highly digestible, low fat diet.   Possible complications include secondary bacterial pneumonia, intussusception (prolapse of one portion of the intestine into the lumen of an adjoining segment of intestine), and septicemia (systemic bacterial infection).  This is another reason to keep puppies being treated for parvovirus in the hospital.

It is important to vaccinate appropriately for canine parvovirus.  Puppies that are vaccinated with reputable vaccines at the appropriate age intervals should be protected from parvovirus.   75% of puppies vaccinated with efficacious products will have developed immunity at 12 weeks of age.  Vaccination is not an effective control method in contaminated environments.

Q:   Can my puppy transmit parvovirus to my cat?

A:   No, canine parvovirus is specific to dogs, but there is a similar, related virus in cats.  This virus is called feline panleukopenia virus and causes similar symptoms in cats as parvovirus does in dogs.

Kittens between 8 weeks and 6 months of age are most susceptible to develop severe disease.  Adult cats often have mild or subclinical infection.  Exposure to this virus (like parvovirus in dogs) is more common in a shelter or cattery.  The onset of disease is sudden and includes symptoms similar to parvovirus in dogs (vomiting, diarrhea, anorexia and lethargy).  Dehydration occurs rapidly and may be severe.  Kittens may be infected in utero or neonatally can develop cerebellar hypoplasia (stunted development of the cerebellum portion of the brain).  This causes a drunken-like walk and incoordination.

The main principles of treatment are rehydration with electrolyte balancing via intensive intravenous fluid therapy in the hospital.  Sometimes, whole blood transfusions are required if plasma protein or total White Blood Cell Counts decrease enough.  The virus remains infectious in the environment for years unless the premises can be adequately disinfected with bleach solution.

Patients should be monitored for hydration status, electrolyte balance and Complete Blood Cell Counts.  Most cases are acute and last only 5-7 days.  If death does not occur during this time, recovery is usually rapid and uncomplicated.  Concurrent upper respiratory infections may occur which makes the prognosis worse.

Green cleaning products are gaining popularity, but owners should know that even environmentally friendly products may pose threats to pet health. “People expose their animals without even realizing the risk,” said Karl Jandrey, an emergency and critical care veterinarian at the University of California, Davis’ Veterinary Medical Teaching Hospital. Veterinarian Camille DeClementi, a senior toxicologist with the ASPCA’s Animal Poison Control Center, said any product with a warning for children isn’t appropriate for pets and recommended keeping animals away from any cleaning activity. San Jose Mercury News (Calif.) (free registration)/The Associated Press

LOS ANGELES—As the time nears for spring cleaning and companies offer more environmentally friendly alternatives to toxic cleaners, veterinarians say pet owners should keep in mind that what’s green to a human can be dangerous—even deadly—to animals.

“People expose their animals without even realizing the risk,” said Dr. Karl Jandrey, who works in the emergency and critical care units at the Veterinary Medical Teaching Hospital at the University of California, Davis. “That’s the most common thing that happens when you come to our emergency room—the clients put their pets at risk because they were unaware of how significant the damage could be.”

Most household cleaners are safe if used as directed on labels, but pet owners who make their own cleansers using natural ingredients don’t have the warnings or instructions that come with commercial products.

Cats, for example, can get stomachaches from essential oils added for orange, lemon or peppermint scents in cleaners, said Dr. Camille DeClementi, a senior toxicologist at the Animal Poison Control Center run by the American Society for the Prevention of Cruelty to Animals in Urbana, Ill.

Most commercial green products are safe for animals, DeClementi said, but owners should still exercise the same precautions as with chemical alternatives, such as keeping pets away from an area being cleaned, not using sprays directly on a pet and making sure that dogs don’t chew on the

products.

If a product says “Keep out of reach of children,” keep it away from pets too, DeClementi said.

Caroline Golon, an Ohio mother of two children under 5 and owner of two Persian cats, said she became concerned about cleaning products before her children were born, when she noticed how often the cats jumped between floors and counters. The Columbus resident uses only unscented green products or vinegar and water to clean, a water-only steam mop on floors and washes the cats’ dishes and litter boxes with hot water and green dish soap.

“There are varying degrees of green, and there are a lot of mainstream brands now that have a green version. You have to do a little research to see what you like best,” said Golon, a pet blogger.

The “green” label on products can be misleading because it still can be dangerous, Jandrey added. “Some still have their own toxicities. In general, they probably are a little less toxic, but not free of toxic potential. They just have a need for a larger dose to cause the same kind of symptoms,” he said.

He cited antifreeze as an example. The pet-friendly version of antifreeze, propylene glycol, is “still an antifreeze product. It’s still intoxicating to patients, our dogs and cats. It’s just not as intoxicating as ethylene glycol.”

It takes more of the propylene glycol to be as deadly as the ethylene glycol, “but it is still intoxicating though it might say pet-friendly in the ads or on the bottle,” Jandrey said.

Labels can’t always account for every reaction, Jandrey said. “Each intoxicating product has different concentrations and each dog or cat, each species, has a different sensitivity to that product. So what might be intoxicating to a dog is really, really intoxicating to a cat because cats might be more sensitive,” he said.

Nancy Guberti, a New York City nutritionist and healthy lifestyle coach for the past 15 years, said some products will say green when they are not.

“Natural means nothing. The consumer has to be educated. It’s all about awareness,” she said.

Extra care also should be taken when cleaning around a pet’s area, such as its toys or bedding, the experts say. Don’t use fabric softener sheets that contain cationic detergents because they will give your pet—especially cats—stomach distress, DeClementi said, referring to a type of chemical soap that kills bacteria.

Such detergents and soaps, normally associated with helping to get clothes clean and fresh-smelling, can have chemicals that can sicken humans and pets alike.

Guberti switched to green cleaners out of necessity when her youngest son developed a liver disorder and many allergies. Guberti said the whole family became green—even their family’s 6-year-old Shih Tzu, Flower, because her son can’t hold Flower “if she is full of toxic chemicals or perfumes.”

She recalled how she took the dog to a groomer for the first time, and Flower came out covered in perfume. Guberti washed her again at home, and now she brings her own bottles to the groomer.

“I have a bottle of shampoo and a bottle of conditioner with her name on it. I always remind them: ‘No perfumes whatsoever,'” Guberti said.

Golon, who uses a maid service once a month, said she had the same problem when they brought their own products when they first started cleaning the house.

“I hadn’t thought about it but the smell was so overpowering, it really bothered me. I can just imagine what it was doing to the cats with their sensitivity to scents,” she said.

Large-breed dogs age faster than small-breed dogs, and larger breeds’ risk of death increases more with age than it does for small breeds, according to a recent study of 56,000 dogs representing 74 breeds. The study found that a 4.4-pound increase in body weight is associated with lowered life expectancy by one month. The researchers plan to study the leading causes of death among large-breed dogs. LiveScience.com

Big dogs apparently die younger mainly because they age quickly, researchers say.

These new findings could help unravel the biological links between growth and mortality, the scientists added.

Normally, across species, larger mammals live longer than their smaller counterparts; for instance, elephants can get up to 70 years old in the wild, while house mice reach only 4 years. Puzzlingly, within species, the opposite seems true — in mice, horses and perhaps even humans.

The apparent cost of bigger bodies is especially conspicuous with dogs, a species that people have bred over the millennia to come in an extraordinary range of sizes. The heaviest known dog may have been Zorba, an English mastiff that weighed 343 pounds (155 kilograms), while the smallest dog alive may be Meyzi, a terrier less than a quarter-pound (110 grams) in size.

Large breeds often die young compared with smaller ones, with a 155-pound (70-kg) Great Dane having an average life span of about 7 years, while a 9-pound (4-kg) toy poodle can expect to live up to 14 years. [The 10 Most Popular Dog Breeds]

To shed light on the possible tradeoffs of large size, researchers analyzed ages at death in 74 breeds, using data from more than 56,000 dogs that visited veterinary teaching hospitals. The researchers focused on why large dogs lived shorter lives on average.

“My main scientific interest is life-history evolution. I’m also a bit of a dog nerd in private life,” said researcher Cornelia Kraus, an evolutionary biologist at the University of Göttingen in Germany.

The scientists found that large breeds apparently aged at faster rates; the speed at which the risk of death increased with age was greater with larger breeds than smaller ones. Indeed, among dog breeds, an increase of 4.4 pounds (2 kg) in body mass leads to a loss of approximately 1 month of life expectancy.

“Their lives seem to unwind in fast motion,” Kraus told LiveScience.

The investigators now want to follow the growth and health histories of a large number of dogs and pinpoint the leading causes of death for large dogs. For instance, bigger canines apparently suffer from cancer more often, which could make sense; large dogs grow more than smaller breeds do, and cancer is rooted in abnormal cell growth.

“This research should be feasible in dogs, since I found that dog people in general seem very open, interested in and interested to contribute to research on their favorite species,” Kraus said.

Kraus and her colleagues Samuel Pavard and Daniel Promislow detailed their findings in the April issue of the journal American Naturalist.

David Alvarez has a real love for his minpins.  He got his first dog Coco about four years ago and loved her personality so much that he didn’t hesitate when his cousin called offering to give him another one.  She had two little, active girls and having an active minpin in the house just wasn’t a good fit for her.  So, last summer David brought home his second minpin and promptly named her Kiki.

Sure enough, Kiki has a spectacular personality of her own.  Quiet during the day when she and Coco are home alone, Kiki becomes energetic and up for anything when David arrives home.  As soon as Kiki sees the leash, she goes bonkers with anticipation for the walk to come.  Usually David takes his two dogs for a long walk down to a cove near where he lives and lets them run around.  The favorite part of his day is seeing Coco and Kiki tearing off after each other.

About a week after David brought Kiki home, Kiki began vomiting and stopped eating and drinking.  Concerned, David brought her to his vet at Santa Margarita Animal Care to see if they could discover what was wrong with her.  Dr. Amy Parker was the attending veterinarian on this case and remembers it well.

When I felt her belly, I could feel a little mass effect in her abdomen associated with her GI track,” recalls Dr. Parker. “David had told me that she had torn apart a peepee pad and we worried that perhaps she had eaten some of that.  We wanted to do x-rays, at which point David informed us that he was financially constrained and probably wouldn’t be able to afford much.  Since Kiki was just a four month old puppy, we wanted to find a way to work with her and David, so we went ahead and ordered the x-rays which ended up indicating that she had a foreign contaminant in her body.”

The cost of the surgery was far beyond anything David could afford on his own. Although he just started working at the time he first got Coco, David’s finances were still in a bind.  David didn’t know what to do and couldn’t bear the thought of letting Kiki go.

“I told Dr. Parker I didn’t have any money, says David.  “When they told me that they would help me and that there were some foundations that might be able to help, too, I just couldn’t believe it.  They asked me to fill out paperwork, which I did right away, and I worked out a plan with them to get Kiki the help she needed”.

Between Santa Margarita Animal Care, the Angel Fund, and David, enough funds were collected to enable the surgery that Kiki so desperately needed.  Thankfully, the operation was a success and Kiki is back to running around the cove with David and Coco.

“We were very grateful to be able to help David,” says Dr. Parker.  “We just couldn’t euthanize this four month old baby, and this owner is working and trying to make a great life with his pets.  We wanted to help him in any way possible and we’re thankful the Angel Fund was part of that.”

David echoes the feeling of gratitude and has a message for Santa Margarita Animal Care and the Angel Fund. “I want to say thank you for helping me keep my pet around.”  He says, “She’s my companion, and it means the world to me that there are people out there who are actually willing to help other people with their difficult situations.”

Since Murph was a special needs dog since puppyhood and neurological issues, it probably took everyone much longer to figure out that something was wrong.

Murph developed a strange awkwardness with his right front foot.  At first he seemed to just be swinging his foot out wider than his normal clumsy gait.  When x-rays were taken, Murph was diagnosed with bone cancer and it had already spread extensively to his lungs resembling a “snow storm”.

We entered Murph into Pawspice right away during our first visit because he had advanced metastatic bone cancer. Murph’s family wanted to help him live as long as possible with no pain and with a good quality of life.  We started gentle combination treatment.  Murph received a few palliative radiation therapy treatments to his bone cancer lesion on his right front foot.  He also received gentle oral and IV chemotherapy and immunotherapy with T-Cyte and supplements.

To our delight and surprise, Murph’s lameness went away and he was feeling great.  It was a joy to see that Murph’s awful pain was gone; the swelling of his right front paw and wrist was gone and he appeared to be back to his normal happy self.  At his 9 week recheck chest x-rays, we had the most amazing and surprising find!  Murph’s new chest x-rays were almost completely clear!

The horrible snowstorm of tumors in his chest had disappeared!  What a happy surprise for all of us to win such unexpected good news for Murph.

Another big bonus was that Murph, who seemed defensive at first, started to always feel just great during his cancer treatment visits at our Pawspice practice at ACCESS in Woodland Hills, CA.  as long as one of his stuffed toys was nearby!

Sadly, after having enjoyed his remission for several months, Murph’s chest tumors returned with vengance.  Of course, we never expected Murph to go into remission and thrive with advanced bone cancer but he did just that for months before his bone cancer was able to complete it’s fatal agenda.

That goodness Murph’s family had th courage and compassion to provide him with the final act of kindness, the gift of a peaceful and painless passing, with the gift of euthanasia when he needed it.

More than half of cats are overweight, says the Association for Pet Obesity Prevention, and the number of portly felines is up 90% from 2007, according to a report from Banfield Pet Hospital. Obesity can lead to health problems for cats, such as diabetes and arthritis, but the condition is preventable. This article lists some ways to help keep cats fit and trim, including regular veterinary exams, exercise and appropriate diet. ChicagoNow.com/Steve Dale’s Pet World blog

Loads of Americans have developed spare tires around their middles, and so have many of our pets. Cats are particularly portly; about 55 percent of tabbies are tubby, says the Association for Pet Obesity Prevention. Some suggest this is a conservative number.

According to the Banfield Pet Hospital 2012 State of Pet Health Report, there’s been a whopping 90 percent rise in overweight and obese cats since 2007. Yet, nearly 70 percent of cat owners say their purring pal is purr-fectly svelte. Cats don’t become hefty overnight, so some owners just can’t tell; without visiting a veterinarian, they have no idea what their pet weights. Other owners have a skewed idea of what cats should look like, thinking tubby is cute. Still other owners are simply in denial.

In any case, the rise of portly cats has become epidemic, and the impact is undeniable. Diabetes and arthritis have never been so prevalent in cats. In fact, behavior problems — which can lead to euthanasia — may be more common in overweight cats. For example, weight gain may contribute to arthritis, so it hurts kitty to step into the litter box or walk up/down the stairs leading to the box. Some pudgy cats can barely fit into a litter box. As a result, some have accidents and are relinquished to shelters or simply left outdoors to fend for themselves.

Some cancers are associated with obesity, and a lack of mental and physical exercise may heighten the probability of cognitive dysfunction (dementia) in older cats. Obese cats also have difficulty grooming themselves.

So, why are there so many tubby tabbies today? There are several explanations:

1. Spay/neuter: More cats than  ver are being spayed or neutered (about 90 percent), which is good. However, there’s a consequence to these procedures, which is seldom discussed. Cats who’ve been “fixed” do experience a drop in energy needs, yet tend to be hungrier. As a result, they have a tendency to beg for table food, or even cat food, often “training” their people to give it to them. This eventually becomes a vicious cycle: The cats pack on pounds as their metabolism slows, making exercise less likely, further boosting weight gain.

2. Free feeding: Leaving food out 24/7 in multi-cat homes makes it impossible for owners to keep track of which cat has eaten what. Cats do train us very well as their automatic food dispensers.

3. Indoors only: Studies show outdoor cats spend about 17 percent of their time traveling/hunting. Indoor-only cats are safer, but do spend far more time catnapping.

So, what to do? Exercise isn’t only important for dogs and people. Use an interactive toy to engage your kitty. Hide food treats in puzzle balls and toys around the house when you’re not home so your little lion can “hunt.” Enrich your cat’s environment by providing toys and lots of places to climb and scratch. Note: Toys can be as simple as an empty box or plastic cap from a milk bottle.

Some indoor cats enjoy walking outside on a leash and harness. “Catios” are the cat’s meow — a trend in New York City and elsewhere whereby patios and porches are enclosed, keeping felines in and potential predators out. Learn more about enriching your pet’s environment in a free handout from the Ohio State University College of Veterinary Medicine,  Dr. Tony Buffington’s Indoor Pet Initiative.

For spayed/neutered cats yet to win the battle of the bulge, there’s good news. The new Spayed/Neutered cat food from Royal Canin provides a unique blend of appetite-curbing fibers, and the donut-shaped kibble slows down cats’ eating, (There’s a Spayed/Neutered diet available for kittens to senior cats, all age groups.)

Remember that a year in a cat’s life is equivalent to about four or six human years. Make sure your pet sees a veterinarian at least once a year for preventive care, which includes being weighed. Owners are often unaware their cat has become plump. Veterinarians are the best source of advice on weight loss. Beware: Crash diets may cause fatty liver disease, which can be fatal.

Diabetes can be difficult for pet owners to recognize (another reason for veterinary visits). Diabetic cats do require insulin, such as ProZinc, specifically created for cats. It turns out that with exercise and a high protein/low carbohydrate diet, weight loss may follow, and some cats then go into remission.

Through diet and scheduled feedings, even spayed/neutered cats may not be so determined to eat. And for those who are already rotund, veterinarians can create a plan to enhance your cat’s quality of life, and maybe even extend the pet’s life.
