She sleeps morein the daytime, but less at night. Obviously, her owner is sleeping less. In the past, there was no clear-cut explana- tion for these nonspecific behavioral changes in older dogs. Todaythereis a possible cause of a decline such as Lucy's. The loving dog who is “no longer herself" may have a condition called canine Cognitive Dysfunction Syndrome (CDS) or “old dog syndrome.” A new pill mayoffer relief for these canine seniors. Earlier this month, the federal Food and Drug Administration approved two drugs to treat two behavorial problems in dogs. One, Clomicalm (clomipramine hydrochloride), is for separation anxiety in pups 6 months and older, The other, Anipryl (selegiline hydrochloride, L-deprenyl), offers possible relief from CDS. Researchers believe CDS, similar to Alz heimer's disease in humans, is caused by physi cal and chemical changesthataffect brain func: tion in older dogs. In one study at the University of California- Davis, 62 percent of 11- to 16-year-old dogs had symptoms in one or more categories of CDS. The prevalence of symptoms rose markedly with age. In a pet-ownerstudy, nearly half ofall dogs 8 years and older were reported to haveat least one symptom associated with CDS. Sugar House Veterinarian Hospital in Salt Lake City is conducting an Anipryl study in conjunction with the manufacturer, Pfizer Ani- mal Health. So far, veterinarian James B. Bar. ton has recruited three dogs, ranging from 15 to 17 years old,for the study. Those dogs, along with three others Barton hopes to include if they meet the study criteria, will receive free blood tests and medication for three months, Although Barton's study will be limited to six animals, he and other Utah vets can prescribe Anipryl to dogs determined to have CDS. Because CDS is a syndrome (a collection of signs) no two dogs have the same signs. In the past, veterinarians have not had a diag. nosis for what is now CDS. “Wejust called it senility or the aging process,” said Barton “These older dogs have been around a long time in people's lives. It's that human bondrelationship that we all enjoy and that's why we have pets. But with aging, these relationships can start to get strained.
