Is Early Neutering Hurting Pets?January 16, 2012Early neutering has become the norm in the U.S. Some states are asking voters to pass initiatives requiring citizens to sterilize their pets no later than puberty. Overpopulation is the driver. But what if large-scale studies found that early neutering jeopardizes the health of our pets? What if we found enough epidemiological evidence that early neutering of pet dogs may open them to orthopedic, behavioral, immunologic and oncologic issues? A veterinarian who treats canine athletes has raised questions about early neutering. In an opinion article, Christine Zink, DVM, Ph.D., Dipl. ACVP, weighs the advantages and disadvantages of early versus late neutering when considering the performance and health of canine athletes. The article, “Early Spay-Neuter Considerations for the Canine Athlete: One Veterinarian’s Opinion,” appears on Dr. Zink’s website. Click here to review the thought-provoking article and to look at the references. Zink assembled 18 references to support her article. Some show that dogs spayed or neutered early are taller than dogs spayed at an older age. Zink notes that sex hormones have a role in bone density. She concludes that the structural and physiological differences in dogs neutered early may be the reason veterinarians are seeing a …

Supplement Can Bolster Pets’ Anxiety TreatmentJanuary 5, 2012When it comes to pets, fears, anxieties and phobias are more common than most people realize. In people—at least some of them—logic and reasoning can be used to help that person understand that an object, noise or event is not as scary as it may seem. But for pets, their perception is their reality. No amount of discussion or psychotherapy can change their minds about a situation that seems threatening or dangerous to them. In a national online survey about anxiety in pets, nearly 40 percent of pet owners who responded say they have at least one pet that experiences anxiety.1 Possible contributing factors to anxious behavior may be a lack of proper socialization, some traumatic event, genetic predisposition, and even cognitive decline. As an animal ages, hearing and sight may be compromised, and with confusion or even discomfort from arthritis, that can result in a more stressed or anxious pet. Nearly a third of the owners who responded to the online survey say their pets’ fears and anxieties are “extremely or very” problematic, while 44 percent say it is “somewhat” problematic. And 70 percent say the anxiety their pet experiences occurs “fairly often” or “frequently.” It …
Let’s Regard End Of Life As A Distinct StageJanuary 4, 2012 While I discussed end of life (EoL) care with Dr. Don DeForge on Connecticut radio, an exciting idea flashed through my mind. We were finishing a 45-minute discussion when I said, “It is time for us to declare, once and for all, that end of life is a distinctly new stage of life. Veterinarians were taught to support four main stages of life. We were not educated to focus our professional attention and develop the skills and expertise for the very important and inevitable ‘End of Life Stage.’ “We need to provide more EoL services because society’s human-animal bond demands more care in this area despite the recession and fewer office visits.” The main life stages we are educated to support are: • Puppy and kitten stage • Adult stage • Senior stage • Geriatric stage I propose a fifth life stage, the End of Life Stage. It is the only life stage that can occur during the other stages. With luck, EoL may not impose itself on the kitten and puppy stage, but sometimes it does. Let’s start thinking about EoL as an inevitable life stage that deserves more focus and expertise in management. …
Brave New World In Veterinary MedicineNovember 30, 2011 North Carolina State University is the only university in the country to offer autologous bone marrow transplants (BMT) for dogs with lymphoma—one of the most common canine cancers. Steven Suter, VMD, MS, Ph.D., Dipl. ACVIM (Oncology), an assistant professor of oncology at North Carolina State University, has been performing the transplants since October 2008. He says that a 40-50 percent cure rate is reported in humans with B-cell lymphoma using the same procedure, although the canine data is still tentative. “When do you say a dog is cured?” Dr. Suter asks. “For people it is five years out [after the transplant procedure]. For dogs I estimate we can say two years after treatment is a success. In the first group of 24 dogs with B-cell lymphoma that we treated, eight are long-term survivors.” Suter started providing this service with the hope that the procedure could be perfected and performed in the specialty clinical setting. Since the inception of the project, Suter has continued to modify the protocol. Apply: The rehydrated graft is applied into a surgery site. If a surgery site is not very vascular, pre-mixing with patient blood is advised. “We …
Nutrition And Advanced Diagnostics Can Combat Parasite Plagues, Other GI ConditionsNovember 9, 2011 Primary care veterinarians and internal medicine specialists alike say gastrointestinal (GI) disease comprises up to 25 percent of their caseloads. Diagnosing and treating the array of chronic cases can be complex. With new pet foods created to prevent or maintain certain GI conditions, new in-house testing and diagnostic tools, more patients and clients can eliminate acute disease or minimize symptom flare ups in maintaining chronic cases. “Parasites, digestive disturbances and food allergies are the most commonly seen GI issues,” says Cade Wilson, DVM, of Carter County Animal Hospital P.C. Ardmore, Okla. “But giardia, GI cancer, GDV are other conditions that require more work to treat. Giardia could be difficult to identify before the new SNAP giardia test was developed and chronic conditions require diagnostic tools or surgery to identify.” Richard E. Goldstein, DVM, Dipl. ACVIM, Dipl. ECVIM, associate professor of small animal medicine at Cornell University, says SNAP tests such as the giardia and pancreatitis tests have brought testing in-house, minimizing missed disorders/diagnosis and expediting treatment. “It takes less than 10 minutes to get a result from SNAP tests,” Dr. Goldstein says. “The shelf life is good and they’re economical. They’ve improved patient care for …
Diabetes UpdateOctober 31, 2011 Diabetes mellitus affects 1 in 400 cats and is on the rise, possibly because of increased obesity rates, according to Morris Animal Foundation. Intervet Schering-Plough, now owned by Merck Animal Health, makers of Vetsulin (porcine insulin zinc suspension), says about 1 in 500 dogs suffer from the signs of diabetes mellitus. A Merck market study of more than 200 veterinarians showed that 70 percent had between one and 10 diabetic canine patients, while 26 percent said they treat 11 or more diabetic canine patients. With such a significant number of feline and canine patients affected by the disease, primary care veterinarians and specialists alike have voiced concern about a significant industry issue—the availability of insulin brands they have grown to rely on. “There’s always a concern that something will go off the market,” says Richard Goldstein, DVM, Dipl. ACVIM, Dipl. ECVIM, associate professor of small animal medicine at Cornell University in Ithaca, N.Y. “The trend in human medicine decides if an insulin brand will be available for veterinary use, considering many insulin forms vets use are actually created for the human market.” Dr. Goldstein says human medical practitioners are trending toward using combinations of short- …
The Health Benefits Of Therapeutic FastingJuly 11, 2011 Fasting and the calorie restricted diet have both shown benefits for human and animal health as well as a lengthening of lifespan.1 Fasting consists of stopping food, but there are a number of variations that allow the consumption of juice, supplements or other items. Calorie-restricted diets usually aim to reduce the caloric intake to 70 percent of what is considered “normal,” either on a daily basis or by alternate day extreme restriction. For humans, multiple nutrient-dense foods are consumed, with an emphasis on fruits and vegetables. For animals, calorie restriction research usually involves restricting the diet to 70 percent of whatever the control animals are eating. Even without an increase in nutrient density, these animal studies show improved health, less degenerative disease and increased lifespan. Calorie restriction induces a cellular response that results in decreased free radical production, increased resistance to free radical effects and production of other protective proteins.2 Oxidative stress resulting in clinical3 or subclinical chronic inflammation is considered to be the primary cause of aging and age-related degenerative disease.4,5 Ironically, as the benefits of fasting and a calorie-restricted diet gain increasing research support, both the human and the …
Update: Pfizer Discontinues Periodontitis VaccineApril 29, 2011UPDATE: 4/28/11 -- Pfizer Animal Health’s canine Porphyromonas vaccine has been discontinued, effective early April 2011, due to efficacy issues. The product was designed as an aid to preventing periodontitis. The Porphyromonas Denticanis-Gulae-Salivosa Bacterin vaccine was conditionally licensed by the U.S. Department of Agriculture in September 2006. Since then, the Madison, N.J.-based company has conducted a 48-month field efficacy study intended to support the full licensure of this product. Although the study confirmed the vaccine’s safety, it “did not demonstrate a vaccine effect in vaccinates (as compared to controls) for either of the key efficacy variables assessed (attachment loss and gingival bleeding index),” according to a letter sent to veterinarians in early March by Oliver Knesl, BVSc, MRCVS, marketing manager of companion animal biologicals at Pfizer Animal Health. On the basis of these results, Pfizer Animal Health will not pursue renewal of the current conditional license for the vaccine, Sherry Podhayny, VMD, told Veterinary Practice News. Dr. Podhayny is the manager of veterinary operations of companion animal biologicals at Pfizer Animal Health. Any product still …
Assistance Dogs: Special Role Of VetsMarch 23, 2011 With the number of assistance dogs growing exponentially throughout the U.S., veterinarians can expect to see more assistance dogs in their practices. While dogs for the visually impaired predominate, dogs can learn to serve an ever-broadening list of disabilities, from hearing impairment to autism and post-traumatic stress disorder for combat veterans and other trauma victims. Service dogs are also trained to work with people who use wheelchairs, need seizure alert or response, need alerts to other medical issues such as low blood sugar, or have psychiatric disabilities. These amazing dogs can retrieve objects out of reach, pull wheelchairs, open and close doors, turn light switches off and on, bark to indicate that help is needed, find and lead another person to the handler, provide balance and counterbalance for those who need help walking and many other tasks. In short, these animals can enable people to live fuller, more independent lives. And the high personal and economic value placed on these dogs calls for extra attention to their health and well-being. For 25 years I have been on the board of directors of the National Education for Assistance Dog Services (NEADS.org), the oldest hearing-ear dog program …
Nutrigenomics Takes ‘You Are What You Eat’ To New LevelFebruary 14, 2011 Veterinary nutrigenomics combines genetics and nutrition to develop optimal diets for companion animals, a field in which researchers and pet food manufacturers are investing significant amounts of time and money. At the University of Illinois, Kelly S. Swanson, Ph.D., and his team are using DNA-based sequencing techniques to characterize the canine and feline gastrointestinal tracts. They are looking at what happens in tissue when animals are fed one diet versus another. The results may lead to a better understanding of the microbial profile and metabolic pathways of animals with varying dietary regimens and at different stages of health and life. Many questions need to be answered before the ultimate goal can be achieved: creating individual diets that make optimal use of, and even manipulate, gene expression. “The dog and cat genome sequence data is being utilized in research, taking genomic biology to gain a better understanding of dog and cat physiology and how nutrition contributes to health and disease,” says Dr. Swanson, an assistant professor of animal and nutritional sciences in the , department of animal sciences. “Genomics in pets is being used to study microbial populations and gene expression changes in blood and various tissues. …
