The skinny on chocolate: Is it actually harmful for dogs?

It’s the theobromine in chocolate that is toxic for dogs, writes veterinarian Julianne Miller, and theobromine levels vary depending on the type of chocolate. Even if an animal doesn’t ingest a toxic dose, Dr. Miller says chocolate can cause diarrhea, vomiting and pancreatitis, so any ingestion should be evaluated by a veterinarian. Also in this article, Dr. Miller explains the importance of vaccinating indoor cats. The Arizona Daily Sun (Flagstaff)

Q: I have heard that chocolate is toxic for dogs, but my dog has gotten into chocolate before and has not had any problems. So I am curious to know if chocolate is actually harmful or not?

A: The simple answer to your question is yes, chocolate is toxic; however, it is the ingredient theobromine that is contained in chocolate that is toxic to dogs. The toxicity is based on the amount of theobromine that the animal ingests when compared to the animal’s weight. It also matters what type of chocolate is ingested because the amount of theobromine in chocolate varies.

Any dose of theobromine over 45 mg/kg is potentially toxic and possibly lethal for dogs and should be treated aggressively by your veterinarian.

As an example, milk chocolate contains 44-64 mg theobromine per ounce of chocolate — so an average sized 80-pound Lab would need to ingest approximately 30-50 ounces of milk chocolate for a toxic dose. That is almost 3 pounds of milk chocolate! However, unsweetened baking chocolate contains 450 mg theobromine per ounce of chocolate. That means that same 80-pound Lab would be at a toxic dose after only 3.5 ounces!

So, you can see that the weight of the animal and the type of chocolate determine the toxic dose. Even if your dog eats chocolate and does not ingest a toxic dose there are other serious consequences to eating the chocolate such as severe stomach and intestinal upset, pancreatitis, diarrhea, vomiting and more. Any ingestion of chocolate is bad for a dog; whether it eats a toxic dose, your dog could suffer some serious adverse reactions. Since even a small dose of theobromine is potentially toxic and possibly lethal for dogs, it is recommended that you contact your veterinarian immediately for advice.

Canine post-traumatic stress recognized as disorder

Veterinarians and dog handlers at Lackland Air Force Base in Texas who work with and train combat canines believe dogs are susceptible to post-traumatic stress disorder. Veterinarian Walter Burghardt Jr. estimates that at least one-tenth of dogs returning from active duty have the disorder, which is characterized by sudden attitude changes and inability to perform tasks that were previously routine. Many of the dogs can be rehabilitated with treatment ranging from behavioral training to medication, but some must be retired from military work. Los Angeles Times

 

By Tony Perry, Los Angeles Times

LACKLAND AIR FORCE BASE, Texas — Not long after a Belgian Malinois named Cora went off to war, she earned a reputation for sniffing out the buried bombs that were the enemy’s weapon of choice to kill or maim U.S. troops.

Cora could roam a hundred yards or more off her leash, detect an explosive and then lie down gently to signal danger. All she asked in return was a kind word or a biscuit, maybe a play session with a chew toy once the squad made it back to base.

“Cora always thought everything was a big game,” said Air Force Tech. Sgt. Garry Laub, who trained Cora before she deployed. “She knew her job. She was a very squared-away dog.”

But after months in Iraq and dozens of combat patrols, Cora changed. The transformation was not the result of one traumatic moment, but possibly the accumulation of stress and uncertainty brought on by the sharp sounds, high emotion and ever-present death in a war zone.

Cora — deemed a “push-button” dog, one without much need for supervision — became reluctant to leave her handler’s side. Loud noises startled her. The once amiable Cora growled frequently and picked fights with other military working dogs.

When Cora returned to the U.S. two years ago, there was not a term for the condition that had undercut her combat effectiveness and shattered her nerves. Now there is: canine post-traumatic stress disorder.

“Dogs experience combat just like humans,” said Marine Staff Sgt. Thomas Gehring, a dog handler assigned to the canine training facility at Lackland Air Force Base, who works with Cora daily.

Veterinarians and senior dog handlers at Lackland have concluded that dogs, like humans, can require treatment for PTSD, including conditioning, retraining and possibly medication such as the anti-anxiety drug Xanax. Some dogs, like 5-year-old Cora, just need to be treated as honored combat veterans and allowed to lead less-stressful lives.

Walter Burghardt Jr., chief of behavioral medicine and military working-dog studies at Lackland, estimates that at least 10% of the hundreds of dogs sent to Iraq and Afghanistan to protect U.S. troops have developed canine PTSD.

Cora appears to have a mild case. Other dogs come home traumatized.

“They’re essentially broken and can’t work,” Burghardt said.

There are no official statistics, but Burghardt estimates that half of the dogs that return with PTSD or other behavioral hitches can be retrained for “useful employment” with the military or law enforcement, such as police departments, the Border Patrol or the Homeland Security Department.

The others dogs are retired and made eligible for adoption as family pets.

The decision to officially label the dogs’ condition as PTSD was made by a working group of dog trainers and other specialists at Lackland. In most cases, such labeling of animal behavior would be subjected to peer review and scrutiny in veterinary medical journals.

But Burghardt and others in the group decided that they could not wait for that kind of lengthy professional vetting — that a delay could endanger those who depend on the dogs.

Since the terrorist attacks of 2001, the military has added hundreds of canines and now has about 2,500 — Dutch and German shepherds, Belgian Malinois and Labrador retrievers — trained in bomb detection, guard duty or “controlled aggression” for patrolling.

Lackland trains dogs and dog handlers for all branches of the military. The huge base, located in San Antonio, has a $15-million veterinary hospital devoted to treating dogs working for the military or law enforcement, like a Border Patrol dog who lost a leg during a firefight between agents and a suspected drug smuggler.

“He’s doing fine, much better,” the handler yelled out when asked about the dog’s condition.

Cora received her initial training here and then additional training with Laub at Moody Air Force Base in Georgia. Before they could deploy, however, Laub was transferred to Arkansas, and Cora shipped off to Iraq with a different handler, much to Laub’s regret.

Bittersweet life with elderly dogs fills, tugs at owners’ hearts

Dogs are living longer than ever thanks to better veterinary care, good nutrition and devoted owners who extend their hearts, homes and wallets to ensure comfort for their silvering canine friends. “People who are devoted to elderly animals are very special people,” said pain expert and veterinarian Lisa Moses. “They do the best they can to make their dogs’ lives better for however long they have.” The Boston Globe

 

Life with Dempsey, a blonde Labrador retriever with a soft round head, has changed for Kevan and Sheila Cunningham. The trio once hiked on conservation land near their home in Southeastern Massachusetts. They relaxed in front of the TV as Dempsey curled up in his own chair. They took vacations as a family and slept together in a big bed.

The Cunninghams got the dog when the Lab was 8 weeks old, and they still refer to Dempsey as their “baby.” Fourteen years later the puppy is 98 in human years. Senior Dempsey, arthritic and failing, can’t climb stairs anymore, jump up to the bed, or ride in the car. The beloved pooch has good days and bad.

“He’s hanging in there,” says Cunningham, a judge with the Taunton District Court. “But every day is a little bit different. He does like to get outside and watch the world and he barks occasionally. It’s an elderly type of bark but he still manages to croak one out.”

Living with an elder of any species is heartbreaking, gratifying, uplifting, and patience-trying.  Old dogs have an especially deep emotional pull when they peer up with their sweet, sad, trusting eyes.

“It’s so hard to live with an elderly dog because it’s like a roller coaster, up and down all the time,” says Dr. Lisa Moses, chief of the Pain Medicine Service at Angell Animal Medical Center. The subject is personal for Moses. She has a 16-year-old pit bull, Dora. “What they used to be able to do, what their life used to be like, it’s really hard to set that aside.”

Singer Fiona Apple made headlines last week for postponing the South American leg of her tour so she can stay by the side of her ailing, nearly-14-year-old pit bull, Janet. In an eloquent and lengthy letter to her fans, Apple explained how important this time with her beloved pet is: “. . . I know she is coming close to the time where she will stop being a dog, and start instead to be part of everything. She’ll be in the wind, and in the soil, and the snow, and in me, wherever I go. I just can’t leave her now, please understand. If I go away again, I’m afraid she’ll die and I won’t have the honor of singing her to sleep, of escorting her out. . .”

The Globe’s Brian McGrory wrote a 2004 column, “The Brown Eyes of Wisdom,” an elegy to his golden retriever Harry in the final act. The lead sentence is a weeper: “They should come with a warning label, these creatures. They should come with a label that says you’re going to fall hopelessly in love, only to have your heart shattered before you could ever possibly prepare.” Kevan Cunningham keeps a clipping of the column close.

Old dogs touch a nerve — and the pocketbook. With an eye on burgeoning market possibilities of the senior set, canine product purveyors sell specially formulated kibble, beds, bowls, ramps to get up into the car, harnesses, diapers for incontinence, as well as various supplements, herbs and holistic remedies designed to cosset a senior dog through its last years. Doting owners find it difficult to resist the pitch for anything to help their four-legged family member.

The Cunninghams bought a large therapeutic bed for Dempsey. They changed to a food for senior dogs. On days he shuns the kibble, Sheila makes chicken soup. The Cunninghams lined the tile floor of their kitchen with rubber mats so Dempsey doesn’t slip. They give him fish oil, glucosamine and chondroitin, supplements thought to assuage arthritis. Their veterinarian prescribed a pain medication, which seems to help. Yet, as with every dog, Dempsey has a simple go-to obsession having nothing to do with fancy or expensive: “Bread,” says Kevan Cunningham. “Any kind of bread.”

Jon Comeau, product development specialist for dogs at Vermont’s Orvis Company, says his company’s market expands with the aging dog population.

Dempsey, a 14-year old blonde labrador retriever, rests on his special soft egg crate bed, located at the bottom of the stairs in his home. The bed is situated there because he can no longer climb the stairs, and he likes to hear his owners when they are upstairs.

Dempsey, a 14-year old blonde labrador retriever, rests on his special soft egg crate bed, located at the bottom of the stairs in his home. The bed is situated there because he can no longer climb the stairs, and he likes to hear his owners when they are upstairs.

“We see it in the sales figures that come through,” he says. “Ten years ago, we were selling products to keep dogs off the couch. Now we’re selling products to keep them on the couch.”

Beds are big sellers for elderly dogs with creaky joints. “We have several versions of Tempur-Pedic and regular memory-foam beds,” says Comeau, who touts the advantages of rectangular beds for stiff dogs who won’t curl up because of the pain. Orvis, which claims to have sold the first dog bed in 1976, also sells absorbent covers for incontinence.

According to the latest statistics from a survey of pet owners by the American Pet Products Association (APPA), there are 78.2 million dogs in US households. The numbers give no breakout figures for how many senior dogs are out there but veterinarians and other experts anecdotally agree canines are living longer because of advances in veterinary care, better food, and heightened owner awareness about how to keep a dog healthier longer.

“We’ve seen a real change in the overall life span,” says Dr. Moses.

What is considered geriatric in a dog? The actuarial table depends on size. For small dogs, old age begin after 10. For bigger dogs, after age “8 or 9,” according to Moses, and for “giant breeds (Great Dane, St. Bernard) at 5 or 6.”

Anne Shuhler of Watertown got a jolt when her veterinarian made an offhand remark while examining her “genuine mutt” Sawyer.

“When Sawyer was 8, the vet said something like, ‘Oh well, he’s a senior now.’ ” Shuhler wasn’t ready for the reckoning. “At the age of 8 I hadn’t really thought of him that way. I thought dogs were old at 12 to 15. I know they don’t live forever but I hadn’t moved him into that mental place.”

Since then, Shuhler has made her peace and now refers to Sawyer, a 10½-year-old with shades of German shepherd and collie, as her “old man.” The two hiked in the White Mountains of New Hampshire not long ago.

Admitting age is a human denial trigger, which owners can extend to un-self-conscious dogs. Cristen Underwood, director of marketing for the Quaker Pet Group, says the company’s “Silver Tails” products for senior dogs didn’t sell well at Petco, the pet store chain, because “people don’t want to admit their dog is getting older. It’s hard to make that change into buying senior pet products.”

Underwood says the Silver Tails line, which includes mats with bamboo charcoal inserts to warm furry bodies and infrared massagers, will now go into “boutique” stores where dog keepers have more of a connection to the sales staff.

Yet, Rob Van Sickle, co-owner of the Polka Dog Bakery in Boston’s South End and Jamaica Plain, says any marketing pitch for dogs through their owners can be foolhardy.

“I was just at a trade show in Las Vegas and people were walking around with white poodles that had been tie-dyed,” he says. “There always seems to be a new marketing pitch.” Van Sickle calls the pet industry a “giant marketing engine and everybody’s always trying to build a better mousetrap.”

Unfortunately, no product will make an old dog live forever. And the owner of a senior dog ultimately confronts the grief of loss. Dr. Moses of Angell empathizes. “People who are devoted to elderly animals are very special people,” she says. “They do the best they can to make their dogs’ lives better for however long they have.”

For Kevan Cunningham, it’s simple. He wants to do anything for Dempsey because the old dog gives everything back. “He is so mellow and peaceful and just wants to please us,” says Cunningham. “He’s still there to greet us with a tail wag.”

Dog’s down mood could be a sign of medical condition

When a dog’s behavior changes, it may be due to underlying illness or pain such as from arthritis, veterinarian Alex Herman writes in response to an owner’s concerns about a listless pet. A complete physical exam by a veterinarian along with blood tests and other diagnostics will help determine if illness is present, according to Dr. Herman. Medication, changes in the dog’s environment or behavioral consultation may be needed to help improve the pet’s condition, Dr. Herman adds. San Francisco Chronicle (12/4)

 

Q: Our 12-year-old dog is a mixed breed whom we  rescued from the streets more than 10 years ago. We assume she had been abused  because of her physical condition. She has always been a somewhat moody dog,  often lying curled up in a ball when she is not the center of attention. She has  seen two other pet dogs die, and it seems to have affected her badly each time.  Now she is getting quite deaf and often lies curled in a ball and refuses to use  her beds, preferring the doormat. She seems truly miserable. Do you have any  suggestions for us?

A: It is unclear whether your beloved dog’s  problems are behavioral or medical. Have her checked by your veterinarian with a  physical exam, red and white blood cell count (CBC), and chemistries to check  kidney function, liver function, electrolytes and thyroid level. Her doctor may  also perform a blood pressure measurement, urinalysis and any other tests that  answer questions raised by her exam.

She may be sleeping by the door because it’s cooler and that makes arthritic  joints feel better. She may not want to sleep on her beds because it is  difficult to position herself. Pain is hard to diagnose in dogs because they are  so stoic. Often arthritis pain is interpreted as getting old or being sad or  tired. If her doctor thinks she is uncomfortable, he or she might want to do  joint radiographs or a trial of pain medication. If she has arthritis, a low,  soft bed may appeal to her.

It may be that she has no medical problems and needs more attention. Owning  a dog is a huge time commitment that can dramatically increase when they age.  They require daily involvement in the form of grooming and play, lots of  affection and exercise, which can be difficult for busy families.

If your dog gets a clean bill of health, a consult with the SPCA’s  behavioral service may help you to understand her and improve her quality of  life. Thank you for taking such good care of her.

Owners and veterinarians concur: Preventive care is the best care

Owners and veterinarians are similarly focused on preventive care, including vaccinations and parasite control, writes veterinarian Ann Hohenhaus, who discusses the results of a survey. Owners expressed concern over pet medication costs, but Dr. Hohenhaus endorses veterinary-grade medications, noting the medications are specifically designed for animals. WebMD/Tales from the Pet Clinic blog

 

 

By Ann Hohenhaus, DVM

A recent survey of both pet owners and veterinarians interrogated the pet health issues each group thought were most important. In last week’s post, I discussed the issues from the veterinarian’s point of view. In this blog I will write from the pet owner’s point of view.

Pet owners said they were primarily concerned with vaccinations, fleas and ticks, heartworms, intestinal parasites, and spending money on medications. This list appears to overlap with the veterinary list on the topic of intestinal parasites, and both owners and vets are squarely focused on preventive healthcare; care to keep their favorite furry, feathery, or scaly companion healthy.

Vaccinations

Vaccinations float to the top of most pet owners’ lists because they save pets’ lives. Before vaccinations were available for common diseases like canine distemper and feline panleukopenia, these diseases spread through neighborhoods like wildfire, often resulting in the deaths of many pets. Decreases in the recommended frequency of some vaccines, coupled with the association between injections and tumors, has raised many questions in pet owners’ minds.

Intestinal parasites

Both pet owners and veterinarians agreed intestinal parasite control was an important issue for pets. How could it not be? Intestinal parasites are high in yuck factor, high in pet discomfort, and on the list of diseases people and pets can share.

Fleas and ticks

These critters are very similar to intestinal parasites with regard to yuck factor and pet discomfort. A pet with a flea infestation may mean you also have a house or apartment with a flea infestation since fleas spend more time off your pet than on. Pet owners want to avoid an expensive exterminator bill by preventing fleas on their pet. Pet owners also want to prevent fleas and ticks to protect their pet against diseases like Lyme disease and blood parasites.

Heartworms

Because heartworms are a serious health concern in both dogs and cats, they are an important medical issue for most pet owners. Nearly every state in the United States reports cases of heartworm in resident dogs and cats. This map shows heartworm cases by state.

Year-round heartworm preventative is a “two-fer” since most prevent both heartworms and some intestinal parasites.

Pet medications

Pet owners want the best for their pet. In my mind, the best are veterinary-specific products.  I prefer to prescribe medications developed specifically for veterinary patients rather than human or compounded medications. Veterinary-specific medications assure you, the pet owner, the product has been tested in dogs or cats and will be absorbed, metabolized, and effective in your pet. But, because most pets do not have insurance and medications are paid for “out of pocket,” many times pet owners can be surprised at the cost. As a pet owner myself, I believe that these veterinary-specific medications are worth paying for.

After looking carefully at the two lists of pet healthcare issues, one from pet owners and the other from veterinarians, are they really so different?  Both groups’ lists really have only one item and it’s the same one: healthy, happy pets.

Why cats don’t make it to the veterinarian’s office enough

More dogs get regular veterinary care than cats, writes veterinarian Barry Burtis. He suggests many factors contribute, including cats’ general aversion to traveling in carriers, owners’ mistaken belief that indoor cats don’t need regular veterinary care and the feline ability to mask symptoms. Dr. Burtis emphasizes the connection between regular veterinary care and optimum health for cats. The Burlington Post (Ontario) (11/29)

Statistics tell us that dogs visit veterinarians much more regularly than cats. On the other hand, polls tell us both dog and cat owners equally recognize the value of veterinary care for their pets.

So, why the disconnect? Why do you suppose dogs average 1.8 veterinary visits per year while cats get to see us only 0.7 times a year? Are dogs or their owners just hypochondriacs, excessively worried or anxious about illness and health? Are dogs just wimps — limping, whining and crying with every little ailment? Do dog owners just have huge amounts of money they wish to use supporting veterinary medicine? Do cat owners not love their feline as much as dog owners care for their dog? Are cats more resistant to disease, requiring less vaccination protection or other healthcare advice?

In my opinion, none of the above offers a correct explanation for the difference. No, there are other much more likely reasons.

Here are some that come to mind. Cats are homebodies. Getting into a carrier, in the first place, is not a happy experience for many cats, neither is it fun for their owner. No matter how smooth the ride, few cats love to go in the car. The yowling, scratching and sometimes bad odours emanating from the cat carrier can take the pleasure out of the ride for the cat’s car companions, as well. At the veterinary hospital, the cat’s attitude toward the cat carrier usually suddenly changes. It’s the nearest thing to home in that place. Why would they want to come out and be weighed, poked, prodded or needled? No, when a cat fails to see any benefit or value associated with this experience, their behaviour reflects their concerns. Is there anything to make the experience more pleasant for all? Well, as a start, begin at a very early age and continue through their life to build a better relationship between a kitten/cat and its carrier. Bring it out of storage at times other than just before a stressful car ride. That should make the trip a bit easier. Then it’s going to be up to the owner to realize most everyone experiences a bit of stress when they go to see their doctor.

People sometimes mistakenly believe that because their cat stays inside it really does not need the benefit of vaccinations. I believe this is another reason cats fail to get to see their doctor as often as they should.  However, municipal bylaws mandate that all cats — regardless of lifestyle — must be vaccinated against rabies. Panleukopenia, feline leukemia and the respiratory viruses — rhinotracheitis and calici virus — are all diseases that can be protected against. A veterinarian should determine which ones are necessary for an individual cat.

Do some cat owners just believe it’s too expensive to visit a veterinarian? People are usually thrilled to learn about the medicines, treatments and therapies that are available for their pets these days. Especially now with the availability of pet health insurance, I hope not many cats are failing to get the full benefits of healthcare because of cost.

A perhaps more legitimate reasons for cats and veterinarians not getting together as often as they should is that cats mask their illnesses very well. Cats are predators, but they are also a prey species. In the wild, showing weakness is the best way to hasten your decline. Cats often hide even severe arthritis, because they are moving around usually much less than dogs. Using the privacy of a litter box, instead of urinating on a walk like a dog, means cat owners are probably much less aware of volumes of urine a cat is producing, behaviour when a cat is urinating or the appearance of a cat’s urine. Lumps and bumps on a cat’s body surface may be less quickly spotted than with a dog. When a cat vomits, is it just a hairball or is it vomiting for some other reason and the hair just happens to be brought up as an effect, but not the cause of the problem?

How do we make cats equal opportunity users, with dogs, of today’s healthcare for pets? It’s very easy. Just make sure your cat visits its veterinarian at least once per year. It can receive a general physical examination, be updated on vaccine needs, get reliable, current diet and healthcare advice, all with a minimum of stress and expense.

Scientists work to crack Lyme disease’s genetic code

Researchers at The University of Texas Health Science Center at Houston are working to identify the factors that explain the virulence of Borrelia burgdorferi, the spirochete that causes Lyme disease, which affects animals and an estimated 30,000 people in the U.S. per year. Using advanced technology, the team is testing the pathogen’s 1,739 genes in an effort to find the ones responsible for its ability to spread so readily. The findings are expected to help develop vaccines, diagnostic tools and treatments

ScienceDaily (Oct. 25, 2012) — Investigators at The University of Texas Health Science Center at Houston (UTHealth) have accelerated the search for the bacterial genes that make the Lyme disease bacterium so invasive and persistent. The discovery could advance the diagnosis and treatment of this disease, which affects an estimated 30,000 Americans each year.


The researchers have developed a new technique that allowed them to test 15 times more bacterial genes than had been evaluated in the previous 30 years to ascertain their roles in infection. Findings appeared Oct. 25 in the online journal PLOS ONE.

Scientists hope to use this information to unravel the mystery of how the spiral-shaped bacterium Borrelia burgdorferi causes Lyme disease. Ticks carry the bacterium and transfer it to animals and humans when the tiny spider-like creatures bite. The Lyme disease microorganism was discovered in 1981.

“We believe that this will be one of the most significant publications in Lyme disease in the next several years. This global approach will help ‘move the field forward’ and also serve as a model for other pathogens with similar properties,” said Steven Norris, Ph.D., the study’s senior author and the vice chair for research in the Department of Pathology and Laboratory Medicine at the UTHealth Medical School.

The bacterium can invade almost any tissue in humans or animals and trigger an infection that lasts from months to years. Its symptoms include a reddish rash that often resembles a bull’s eye and flu-like symptoms. The disease can lead to nervous system problems, joint inflammation and heart abnormalities. Most instances of Lyme disease can be treated with antibiotics.

“Our long-term goals are to screen, identify and characterize the virulence determinants of the Lyme disease bacterium and thereby dissect the mechanism of pathogenesis in mammals and ticks,” said Tao Lin, D,V.M., the study’s lead author and assistant professor of pathology and laboratory medicine at the UTHealth Medical School. “With this information, we will have a clearer picture about the virulence determinants and virulence factors for this fascinating microorganism and the mechanism of pathogenesis behind this unique, invasive, persistent pathogen.”

Norris, the Robert Greer Professor of Biomedical Sciences at UTHealth, and Lin are running tests on the 1,739 genes in the bacterium to see which genes impact the microorganism’s ability to spread disease.

To do this, they mutated the bacterial genes and gauged the impact in a mouse infection model. Overall, 4,479 mutated bacteria were isolated and characterized. Whereas it took researchers about three decades to knock out less than 40 bacterial genes, Norris and Lin knocked out 790 genes in a comparatively short period of time; some genes were “hit” multiple times. A newly developed screening technique, which involves signature-tagged mutagenesis and Luminex®-based high-throughput screening technologies, can also be used to identify infection-related genes in other bacteria.

“This kind of study enables us to better understand the disease pathogenesis at the basic level,” said Charles Ericsson, M.D., head of clinical infectious diseases at the UTHealth Medical School. “In time, such understanding of virulence properties might enable us to develop vaccine candidates, better diagnostic tools and perhaps even targeted drug intervention.”

Norris and Lin are on the faculty of The University of Texas Graduate School of Biomedical Sciences at Houston.

Previously, Norris helped develop a method based on one of the bacterium’s proteins, called VlsE, for diagnosing Lyme disease. The test, which is now used worldwide, involves detection of VlsE-specific antibodies, which are often found in people and animals infected with Lyme disease.

Also participating in the study from UTHealth were Lihui Gao, D.V.M., Chuhua Zhang, Evelyn Odeh and Loic Coutte, Ph.D. Mary B. Jacobs and Mario Philipp, Ph.D., of the Tulane University Health Sciences Center collaborated on the study as did George Chaconas, Ph.D., of The University of Calgary in Canada. Mutated strains produced through this study are being made available to the scientific community through BEI Resources.

The study is titled “Analysis of an ordered comprehensive STM mutant library in infectious Borrelia burgdorferi: insights into the genes required for mouse infectivity.” The project described was supported by Award Number R01AI059048 from the National Institute of Allergy and Infectious Diseases.

Birds can get arthritis, too

Osteoarthritis, a painful inflammation of one or more joints, can occur in birds, but careful management by a veterinarian, along with some lifestyle changes, can help affected birds live comfortably, writes veterinarian Margaret Wissman. Diagnostic tests to ascertain the health status of the bird, including blood count, kidney and liver tests and other parameters, will help the veterinarian select the most appropriate medications, Dr. Wissman notes. Owners can make changes such as providing perches of several sizes and shapes and keeping a pet bird’s weight within the normal range to help avoid exacerbating the condition, she advises.
DESCRIPTION OF ARTHRITIS

Arthritis is a degenerative disease of the joints that can be a primary disease or secondary to defects or injury of the joints or supporting tissues. The most common form diagnosed in pet birds is osteoarthritis. Multiple joints are often affected, unless the disease is brought on by trauma. Pain accompanies this joint inflammatory disease.

SYMPTOMS OF ARTHRITIS

This is typically an acquired disease with age but it can be brought on by an injury or if a tumor, either malignant or non-malignant, involves a joint. Infections such as mycoplasmosis can also result in arthritis in pet birds. Affected joints may be red, swollen or hot.

IMMEDIATE CARE OF ARTHRITIS

You should have your bird evaluated by an avian veterinarian who will want to perform tests to ascertain the cause of the joint problems. You may want to purchase braided rope perches or soft synthetic perches, and make sure that you have perches of several different diameters so feet don’t cramp up from always being in the same position on a perch.

LONG-TERM CARE OF ARTHRITIS

Have your bird’s blood count, chemistry profile, kidney and liver checked out before getting a medication prescribed. In some cases, antibiotics or antifungal medications are indicated. There are choices of NSAIDs (non-steroidal anti-inflammatories) to give a bird for long-term arthritis relief; however, most of these medications are not labeled for use in birds. The old stand-by, aspirin, is actually a wonderful anti-inflammatory for birds; however, dosing is critical, so this must be prescribed by an avian veterinarian. Other NSAIDs can also prove useful in the long-term management of arthritis. Narcotics, such as codeine, and steroids are not commonly used for long-term treatment of birds because of potentially dangerous side effects. To keep your bird more comfortable when afflicted with arthritis, provide appropriate perches as well as flat corner perches. Do not let your bird get overweight, as it will bring added stress to already damaged joints. If your bird is already overweight, discuss a long-term diet and exercise plan for your bird with your avian veterinarian.

Just like in people, allergies are a common occurrence in pets

Allergic dogs are common visitors to veterinarian Brian Jenkins’ office, making up an estimated 20% of his clientele, and he can relate to their plight because he also suffers from allergies. The three categories of allergies in pets are flea allergy, food allergy and atopic dermatitis. While there is no definitive cure for allergic conditions, Dr. Jenkins says that with time and consistent treatment, many animals can experience relief from their symptoms.

 

 

Nan Sterner could not figure out what was wrong with Sadie.

Since she was a puppy, the 4-year-old golden retriever and poodle mix – a goldendoodle – was constantly scratching.

“She was itching and scratching all the time,” Sterner said. “I thought it was fleas.”

But Sadie was found to be flea-free. She was still scratching, though, to the point where she had red and irritated patches of skin all over her body, and even had some scratched-open sores.

So Sterner brought Sadie to Aloha Animal Hospital in Hanover to find out what was wrong, and she was relieved to discover that her condition is treatable.

“Sadie has a huge amount of allergies,” said Dr. Brian Jenkins, veterinarian and co-owner of the animal hospital.

Some cats and dogs suffer from allergies, and often are allergic to the same things as people, like trees, grasses, weeds, and pollen, Jenkins said. While people usually suffer the effects of allergies through their respiratory systems, cats and dogs feel it in their skin.

And over the last year, with continuous warm and often wet weather, those allergies seem to be worse, and Jenkins is seeing more and more cases coming into his office all the time.

The good thing is while allergies are no fun, they are treatable.

Treating pet allergies

Even pets who have not shown signs of allergies before might be scratching their coats and looking for relief from the itching this year.

Jenkins said allergies have a threshold. An allergen might have no effect on a dog or cat in a normal year may flare up with more exposure.

Pets typically have three different kinds of allergies. One is a flea allergy, in which they have a reaction to flea saliva.

Along with common allergens, fleas have been thriving with weather conditions over the last year.

A second allergy is one that’s often difficult to diagnose, which is a food allergy. Most allergies start in the first few years, but food allergies can start at any time. Dogs are usually allergic to beef, followed by dairy and wheat. Cats are also allergic most to beef and dairy, as well as fish.

But the third and more common allergy, and the one Jenkins likes to study, is atopic dermatitis – or the skin allergy.

These allergies typically hit pets that are between 6 months and 3 years old. And they can be seasonal, caused by things like weeds, grass, mold or pollen, or they can be caused by things like dust that are present throughout the year. Tree pollens are particularly bad in Hanover this time of year, Jenkins said. And he said he is seeing lot of allergies to ragweed now, too, as well as sagebrush and a whole host of molds and spores.

“You won’t cure an allergy, but you can treat it,” Jenkins said.

One way to treat these is through the use of steroids, which is quick and cheap, but it can have negative side effects, such as ulcers, vomiting, diabetes and skin and coat problems.

Jenkins treats Sadie, and many of the pets he sees, with topical treatments for the skin, as well as allergy shots. It can be time consuming, and a financial commitment, but it’s often the best way to keep allergies under control, he said.

Every pet and each allergy is different, and Sadie is a pretty extreme case, too, suffering from a whole list of allergies, he said. But even with an extreme case like Sadie, and with the help of an owner who constantly monitors and applies medication, treatment can been successful, he said.

A doctor who understands

Allergies are not fun for pets. Or people. Jenkins takes a special interest in treating allergies because he has suffered from them since he was a little kid.

And as an allergy sufferer, he’s empathetic with what pets are going through when they come in his office with allergies.

He’s allergic to many of the same things as Sadie – particularly ragweed, which he said is vicious this time of year.

Like Sadie, he goes to his doctor for treatment, and is able to keep it under control.

Though he’s a general practitioner of veterinary medicine, and does not specialize in allergies, he takes a special interest in it. And with the hundreds of dogs and cats that come through his doors, he said he could open an allergy clinic if he wanted to. About 20 percent of the dogs he sees have some form of skin allergies.

Any breed is susceptible, he said, but allergies are particularly common among golden retrievers, labs, Boston terriers and shih tzus.

But there’s hope for all allergy sufferers.

“Dogs and cats are allergic to many of the same things as people,” Jenkins said. “And they can be treated in some of the same ways.”

While there is no silver bullet to treat all allergies, he said with time, patience, and constant treatment, allergies can be brought under control.

And dogs like Sadie can continue to live happy, itch-free lives

Pancreatitis in pets a common holiday concern

Pancreatitis — inflammation of the pancreas that can be fatal in severe cases — causes pain, vomiting, lethargy, decreased appetite and a fever in dogs and may be caused by ingesting a fatty meal, such as turkey from the holiday table, writes veterinarian Kristel Weaver. Diagnostic tests including blood work and ultrasound help veterinarians diagnose pancreatitis. Treatment involves withholding food to rest the pancreas as well as giving pain medication and antibiotics, according to Dr. Weaver. Cats also can suffer from pancreatitis, but it’s usually not associated with eating a high-fat meal, and cats tend to have more subtle symptoms than dogs

Over the holidays we frequently hospitalize dogs and cats with pancreatitis. Even if your cute little one is looking up at you with big, sad eyes it’s better for them not to eat the greasy turkey leftovers. This month’s article is all about pancreatitis.
What is pancreatitis and what causes it? Pancreatitis results from swelling and inflammation of the pancreas. The pancreas not only produces hormones like insulin but also digestive enzymes. These enzymes are normally inactive until they reach the intestinal tract. But when the pancreas becomes inflamed they activate prematurely and digest the pancreas itself, causing a lot of damage.
How do I know if my dog has pancreatitis? Dogs with pancreatitis vomit, aren’t interested in food, and have a painful belly. They might show their abdominal pain by walking with a hunched back or stretching out in the prayer posture. They might also be lethargic, have diarrhea, or a fever. Your veterinarian will use a combination of history, examination, blood work and ultrasound to diagnose pancreatitis.
How is pancreatitis treated?
Based on severity, pancreatitis is usually treated with a combination of fluids, pain medications, anti-nausea medications, and antibiotics. Food is withheld for the first one to two days to “rest” the pancreas and give it a chance to heal. Moderate to severe cases of pancreatitis require hospitalization on IV fluids, whereas mild cases might be treated as outpatients. Severe pancreatitis can be fatal despite aggressive treatment.
Are some dogs more predisposed to pancreatitis than others? Yes, dogs with diabetes, hypothyroidism, Cushing’s disease, or high lipids are more likely to get pancreatitis. Dogs that are obese or that eat a rich, fattening meal are also predisposed. Dogs who have had a previous episode of pancreatitis are more likely to get it again. Any dog can get pancreatitis and sometimes we cannot identify a reason why.
Do cats get pancreatitis too? Yes! Cats also get pancreatitis. When cats have pancreatitis it is different from dogs in several ways. First, they don’t usually have a history of eating a rich or fattening meal. Second, they often have a chronic problem instead of a sudden attack. Third, they are not typically vomiting and often only shows signs of a poor appetite and lethargy. Diagnostics and treatment are similar for cats and dogs.
If you want to give your pet something special for the holiday buy a special treat from the pet store. It may be hard to resist those pleading eyes but your pet’s health is worth it! I hope you and your entire family have a wonderful Thanksgiving without an emergency visit to the veterinary hospital.
