Continuous improvement in the veterinary care of aging pets and the increasing social acceptance of pets as members of the family have led to a steadily growing population of geriatric pets. As a result, the need to understand and address behavioral issues that arise with senior pets is increasing. Cognitive dysfunction (CD) in dogs and cats, similar to Alzheimer's disease in humans, can cause behavior changes secondary to declines in mental function that are not directly observable.
