DOG COGNITIVE DYSFUNCTION – ALZHEIMER’S IN ANIMALS Linda Juergens, CVT Does your elderly dog seem to be ignoring you? Does he wander aimlessly? Has he lost his appetite? These could be signs of Canine Cognitive Dysfunction. Due to advances in veterinary medicine and the quality care of loving pet owners, dogs are now living longer than ever before. As an animal progresses into its twilight years, inevitable aging changes take place in all organ systems, including the brain. Most companion dogs are considered geriatric when they reach approximately 10 years of age. Many people think that it is "normal" for their elderly dogs to gradually lose energy and interest in life. They therefore tolerate the cognitive aging syndrome for longer than is necessary. The various symptoms and behavioral changes that may occur fall into four general categories that can be abbreviated into the acronym DISH -- disorientation, interaction changes, sleep changes, and house soiling. Unfortunately, there is no test to diagnose Canine Cognitive Dysfunction Syndrome. Therefore, the observations that you, as the pet owner, make at home will be very important with respect to a diagnosis. If you notice behavioral changes in your pet, write down what you have observed and when and where the behaviors are exhibited. Then take this to your veterinarian. In addition to taking a complete medical and behavioral history of your pet and speaking to you about the behaviors observed in the home environment, a veterinarian will also conduct a thorough physical examination, possibly blood tests and urinalysis will be performed to rule out other causes. This is done to rule out other medical conditions that could potentially be causing the observed symptoms. Once underlying diseases have been ruled out treatment can be discussed and pursued. Although there is no cure, there are some treatments available. Medication may be recommended, as well as, specially formulated foods, antioxidants and supplements of omega-3 fatty acids that have both proven effective for some dogs. With these treatments and some changes in environment we can reduce symptoms and improve their quality of life.
