What Cornell describes
Cornell’s Riney Canine Health Center lists cognitive dysfunction syndrome among causes of anxious behavior: the dog paces and pants, particularly at night, is often restless and may seem disoriented. It usually affects senior dogs because of age-related changes in the brain.
Cornell also notes that dogs seldom have “anxiety” alone: something else, medical or behavioral, is often behind it. That is the reason to talk to your vet before assuming age.
What to write down
Time of night the pacing starts and how long it lasts
Staring, getting stuck in corners, or not recognizing familiar rooms or people
Pain, thyroid problems, kidney disease, poor eyesight and hearing loss can all contribute to restlessness. Bring your log and ask for a full senior workup.
Frequently asked questions
Is night pacing in an old dog normal?
It can be a sign of cognitive dysfunction, pain or other medical problems. Record when it happens and ask your veterinarian.
