Doggy Dementia: When an Old Dog Seems Lost at Home

Old age with a name

When a senior dog starts seeming confused — staring into corners, getting stuck behind furniture, or forgetting familiar routines — it may be canine cognitive dysfunction, the dog equivalent of dementia. It's common in older dogs and often mistaken for 'just getting old'.

The signs to notice

Vets use the sign-posts of disorientation, changed interactions, sleep-wake disruption, house-soiling, and altered activity. A dog who paces at night, seems anxious or clingy, or forgets house-training they've known for years may be showing early changes worth raising with your vet.

Rule out the treatable first

Many of these signs overlap with pain, failing sight or hearing, and conditions like kidney or thyroid disease. A vet check matters, because some causes are very treatable — and a dog who can't see or hear well simply needs different help than one who's cognitively declining.

How to help them cope

Keep routines and furniture predictable, add night lights, use gentle daytime enrichment, and don't punish confusion. Your vet may suggest a specific diet, supplements or medication that can genuinely slow the decline and ease anxiety. Many dogs stay happy and comfortable for a long time with support.
