Like humans, dogs and cats can exhibit signs of senior dementia. Vocalizing (barking, growling, howling) for no reason or at all hours, appearing to get "lost" in familiar surroundings, and other personality changes may suggest dementia.
BARRYRUB asks: "My 14 year old mixed cairn terrier is exhibiting odd behavior. He'll stand and stare at nothing for 10-15 minutes at a time. He then wanders aimlessly from room to room before finally settling down for the night. He does appear to be sleeping all night. He also drinks incessantly; bowel and urine seem normal, although he does pee every 15 minutes or so before going to bed. He's done that for years. He eats well, doesn't play much any more. Looked up dog dementia and he does have many, but not all of the symptoms. Any similar situations?" Original post
It is always important to have your pet evaluated by your veterinarian to rule out any medical causes first, as some diseases may cause similar signs or add to dementia behaviors. Learn more about the signs seen with:
