Types of Behavioral Changes in Dogs With Dementia

Aging dogs often begin to display symptoms of Cognitive Dysfunction Syndrome (CDS). CDS is comparable to Alzheimer's disease in humans, and physically degenerates the brain in much the same way. Loss of cognitive abilities and marked change in behavior are the two major features of dementia in dogs. Several symptoms may indicate CDS.

  1. Disorientation

    • Some of the more obvious signs of dementia in dogs involve behaviors that suggest confusion or disorientation. A dog suffering from dementia may seem to be lost in places that should be familiar--aimless wandering, pacing and difficulty finding doorways are all common examples of such behavior. Dogs with dementia may also exhibit some unusual behaviors such as trembling, gazing into space, becoming trapped in corners and startling easily.

    Interaction Changes

    • Perhaps most disturbing to owners of a dog experiencing Cognitive Dysfunction Syndrome is a decrease in the level of play and interaction they once had with their pet. Dogs with CDS may begin to seek less attention. They may become withdrawn, disinterested in play or going outside, and may no longer respond to familiar commands.

    Changes In Eating and Sleeping Habits

    • Dementia may cause your aging dog to sleep through most of the day and pace throughout the night. Interest in food and fresh water may also decrease dramatically. Even offering special treats may not inspire a dog with dementia to eat.

    Soiling Indoors

    • A dog suffering from dementia may also begin soiling in the house. Owners noticing indoor soiling often attempt more frequent visits outdoors, but soon realize that it does not necessarily alleviate this problem. Uncharacteristic indoor soiling should never be reprimanded, as it most always points to a medical condition.
