In August 2010, representatives of the American Heartworm Society (AHS), the Companion Animal Parasite Council (CAPC), and experts in the field of nematode resistance met in Atlanta. Their goal was to discuss the possibility of heartworms becoming resistant to macrocyclic lactones

A surgical procedure used on humans to remove brain tumors that cause Cushing’s disease is now becoming available to dogs, thanks to collaboration between a human neurosurgeon, a veterinary endocrinologist, and a veterinary surgeon in the Los Angeles area.Cushing’s disease (hyperadrenocorticism, or HAC) is an adrenal disorder common in middle-aged and older dogs, affecting an estimated 100,000 dogs per year in the U.S. It occurs when the body produces too much cortisol, causing increased appetite and thirst, skin problems, and muscle weakness. Cushing’s can also predispose dogs to other conditions such as diabetes, pancreatitis, and infections.

Do you have a dog recovering from orthopedic or neurologic surgery, one who has mobility issues, or a senior dog who has arthritis? If so, at some point, you have probably wished you could do something – anything! – to help make your dog's life (and your own) a little easier. I asked two veterinarians who specialize in canine rehabilitation to share some of their top picks for canine assistive/rehabilitative equipment. Laurie McCauley, DVM, CCRT, is founder and medical director of TOPS Veterinary Rehabilitation in Grayslake, Illinois, and is considered one of the pioneers in the field of veterinary rehabilitation. Evelyn Orenbuch, DVM, CAVCA, CCRT, recently opened Georgia Veterinary Rehabilitation, Fitness and Pain Management in Marietta, Georgia, and has focused on veterinary rehab medicine since 2003.

Denise Mankin, DVM, was on duty late one night in a Des Moines, Iowa, emergency veterinary clinic when Yeller, a Labrador Retriever, was rushed in sporting a fresh wound to his back. Yeller had been shot after escaping from his rural home. After stabilizing Yeller with IV fluids, antibiotics, and pain medications, Mankin opened up the dog's abdomen to find blood filling his abdominal cavity. A bullet had perforated Yeller's small intestine in five different locations, and two of the sites were hemorrhaging profusely. Within moments, his blood pressure plummeted. As Mankin worked desperately to tie off the blood supply to his damaged bowel, Yeller went into cardiac arrest. Cardiac drugs restored Yeller's heart beat, and donor blood, having been warmed for transfusion, was pumped into him.

A few months ago, I wrote about the British Kennel Club’s registration of two special Dalmatians over the objections of the breed clubs there (Whole Dog Journal June 2010). These two dogs were the result of a breeding project begun in 1973, in which a single outcross to a Pointer was made in order to reintroduce the normal gene for uric acid back into the Dalmatian bloodline.

Making a fresh look at the things we take for granted can be wonderfully enlightening. Sometimes, the little light bulb overhead begins to sizzle and sparkle, illuminating a new and better way of doing things. Consider this example: When some savvy veterinarians took a fresh look at performing spays, a surgery we've been doing the exact same way for decades, they came up with a revised technique that accomplishes all of the objectives of the spay surgery with fewer complications. How cool is that?

Exciting news regarding bone marrow transplants for dogs with lymphoma has recently emerged. North Carolina State University’s College of Veterinary Medicine in Raleigh is the first university in the world to open a canine clinical bone marrow transplant (BMT) unit. Dr. Steven Suter, assistant professor of veterinary oncology at NCSU, is about to perform his 30th transplant, all done over the past two years. Lymphoma, also called lymphosarcoma, is one of the most common cancers to occur in dogs. While it used to be considered a disease of middle-aged and older dogs, those demographics have changed in the past 5 to 10 years, with more and more young dogs being diagnosed. Golden Retrievers have a particularly high risk for this type of cancer.

In Whole Dog Journal's opinion, annual vaccination for most canine diseases is unnecessary and potentially harmful. Dog owners should avoid employing those old-fashioned veterinarians who recommend annual vaccines. Owners should also avoid those veterinary service providers who provide inexpensive vaccines and other routine care without the benefit of a relationship with you and your dog beyond a brief transaction in a parking lot or pet supply store.

Are the classic plastic cones really all that bad? It depends on which dog you ask. Some dogs seem to accept the weight of the heavy plastic, the restricted visibility imposed by the opaque material, the need for increased clearances around the house, and even being gouged by the thick plastic tabs that are supposed to be belted by the dog's collar at the base of the cone. Today there are a number of alternatives to the classic Elizabethan collars to prevent a dog from licking a wound, aggravating a hot spot, tearing out his surgical stitches, or removing a bandage. The alternatives offer a dog greater comfort, better mobility, and improved visibility.

On December 1, 2009, Merial published an open letter to veterinarians, announcing a shortage of Immiticide (melarsomine dihydrochloride), the only drug licensed for use in treating heartworm infestations in dogs. The shortage is due to a manufacturing site transfer. The company expressed hope that the shortage will not persist beyond the first quarter of this year.

Arkansas canines and their humans have very good reason to celebrate the start of the new decade. That state’s new rule allowing for a three-year rabies vaccine became effective January 1, 2010. This means dogs in Arkansas will need to be vaccinated only every three years (after their initial first-year booster) instead of annually, as was previously required.
