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.

Canine kidney and bladder stones may be painful and life-threatening, but an informed caregiver can help prevent them. By far the most common uroliths or stones in dogs are struvites and calcium oxalate stones. These two types represent about 80 percent of all canine uroliths. Now we address the remaining stones that can affect our best friends: urate, cystine, calcium phosphate, silica, xanthine, and mixed or compound uroliths.

We received the following long – but very informative – letter from Evelyn Orenbuch, DVM, the vice president of the American Association of Rehabilitation Veterinarians. It helps further our readers’ education about their options for treating canine CCL injuries.

Bladder and kidney stones are serious problems in dogs as well as people. These conditions – which are also known as uroliths or urinary calculi – can be excruciatingly painful as well as potentially fatal. Fortunately, informed caregivers can do much to prevent the formation of stones and in some cases actually help treat stones that develop. Last month, we described struvite stones (see Canine Kidney Stone and Bladder Stone Prevention" Whole Dog Journal April 2010). Struvites contain magnesium

Anal sacs are located on either side of your dog’s anus, between the external and internal sphincter muscles. Depending on the dog, they range in size from that of pea to a lima bean. Sebaceous glands within the lining secrete a foul-smelling liquid. Under normal circumstances, the sacs empty on their own during bowel movements via a pair of ducts. This natural, routine emptying serves as a means of olfactory communication and establishing territory. Each dog possesses his own unique scent, which is why ritualized dog-to-dog greetings include copious rear-end sniffing. When a dog presents his rear for information gathering, the muscle movements involved in raising the tail apply pressure to the sac, prompting the release of additional scent.

When you or a loved one develops a medical issue, chances are you’ll be inclined to do some Internet research. While I say, “More power to you!” other medical professionals might roll their eyes at the thought of “wasting” valuable time discussing potentially whackadoodle notions gleaned from cyberspace. Whether veterinarians like it or not, the Internet is here to stay. What can you do to make your online research more productive and your discussions about it with your vet more palatable? Here’s how to find instructive, accurate, credible Internet information while avoiding “online junk food” -and how to comfortably discuss what you’ve learned online with your veterinarian in a way that promotes collaborative discussion. By the way, although I’m a veterinarian teaching people how to better care for their dogs, this information is also applicable to your own healthcare! So, let’s begin. How can you determine whether or not a website is dishing out information that is worthy of your time?

A training friend suggested that I read Low Stress Handling, Restraint, and Behavior Modification of Dogs and Cats, by applied animal behaviorist Sophia Yin, DVM, MS. As an owner whose dogs have taken their fair share of visits to vet clinics, I really liked what I read. Dr. Yin's text takes a critical look at how our pets are often handled in veterinary clinics – and it's not pretty, as you may have seen yourself. Fortunately, she also offers common sense advice on approaching veterinary care so as to make it as stress-free as possible for our pets. Popular myths abound that force is needed to get animals to behave. Instead, Dr. Yin focuses on how to modify behavior quickly in a veterinary setting using a systematic and positive approach. Her methods involve classical conditioning to change the pet's emotional state; setting up the veterinary environment to ensure the pet's comfort; teaching us how to handle animals with appropriate, rather than stronger, restraint; and how to behave around animals so as to avoid creating problems.

Dogs go lame for all kinds of reasons. Arthritis, Lyme disease, paw injuries, muscle sprains, bee stings, interdigital dermatitis, and dislocated kneecaps can make any dog limp. But when an active dog suddenly can't put weight on a hind leg, the most common diagnosis – for more than a million American dogs every year – is a torn cruciate ligament. In 2003, according to the Journal of the American Veterinary Medical Association, the cost of treating those injuries exceeded $1.32 billion, and the price tag keeps rising. The most common prescription for canine knee injuries is surgery. Unfortunately, operations don't always work and some patients, because of age or other conditions, are not good candidates. In recent years a nonsurgical approach called conservative management" has helped thousands of dogs recover from ligament injuries

My dog Ella and I spent an anxious night at the emergency clinic recently, after she found and ate paintballs while on our walk. She was off-lead at the time, so when I realized what she was doing, I had no way of knowing how many she had eaten. In fact, I did not immediately recognize the colorful, marble-sized gelatinous balls, and thought they were some kind of candy. It was only a few hours later, when she threw up bright turquoise, that I became concerned and investigated further. Paintballs ingredients can include polyethylene glycol, dipropylene glycol, glycerol, and sorbitol, all osmotic laxatives, which can lead to hypernatremia (“salt poisoning”) when ingested in sufficient quantity. These ingredients also taste sweet, which is why dogs find paintballs so attractive.
