ASPCA reacts to new
canine diet drug

THE American Society for the Prevention of Cruelty to Animals (ASPCA) has applauded the advances in veterinary science that have resulted in the approval of a diet drug for dogs (Pfizer Inc’s Slentrol) by the US Food and Drug Administration (FDA). However, the country’s oldest animal welfare organization reminds pet parents that this should not replace regular diet and exercise programs; and that it is important to work closely with your veterinarian to determine if your pet would be an appropriate candidate for this treatment.

“In the most recent National Academy of Sciences National Research Council report on the nutritional requirements of dogs and cats, pet obesity was highlighted as an issue that needs to be addressed,” said ASPCA president and CEO, Ed Sayres. “This drug certainly does that, and points to the incredible advances in veterinary science that are turning futurism and fiction into fact, but it is too soon to say what the effects and/or side effects of this drug will be with long-term use in large numbers of dogs.

“However, we want to make clear that the ASPCA does not consider medication a substitute for proper diet and exercise. This treatment should be considered only for seriously obese dogs if regular diet and exercise programs have failed to have an effect, and if a pet’s life is endangered because of its weight. Pet parents should be fully informed to potential side effects and closely involved in this decision to make sure that they are making the best possible decision for their pet.

“The way Slentrol works is to reduce a dog’s appetite and fat absorption to produce weight loss,” said Dr. Steven Hansen, veterinary toxicologist and senior vice-president of the ASPCA’s Animal Poison Control Center, located in Urbana, Ill, and the premier animal poison control center in North America. “A pet’s veterinarian will determine if Slentrol is an appropriate prescription to treat canine obesity based on the pet’s weight and general health. The drug should only be prescribed by a licensed veterinarian after a thorough examination of the pet.”

Obesity in dogs is defined as being 20 percent over their ideal weight. Surveys estimate that five percent of American dogs are obese, with 20 to 30 percent of them overweight. Just as in humans, obesity in dogs can lead to ill health, including joint disorders, diabetes and other problems. Side effects of the drug may include diarrhea, vomiting, lethargy and loss of appetite.

“As with any weight reduction program, Slentrol should be used as part of an overall weight loss and exercise program monitored by your veterinarian,” said Dr. Hansen. “Dogs will typically be prescribed Slentrol for three months and should be re-examined at that point.” Slentrol was expected to be available with a veterinary prescription from about April 2007. - ASPCA press release
