Hide-and-seek for treats offers a new window into cognitive decline in dogs

Reported by Phys.org · October 23 at 1:40 PM · Summary by Pawdeck

University of Arizona researchers have developed CANID, a roughly 40-minute test that uses treat-based games to detect subtle memory and behavioral flexibility problems in dogs. It can flag impairment around age 7 or 8, well before the obvious signs of dementia that usually appear at 12 to 14. The study tested 239 dogs in Tucson and California, with retests at six months and a year.

Background

Canine cognitive dysfunction is a dementia-like condition that becomes more common as dogs age, much as in people. Most existing screening relies on owner questionnaires, which tend to catch problems only once they are already noticeable. Research tools like this aim to detect changes earlier, which may help scientists understand what supports healthy brain aging.

Why it matters

Changes in memory or behavior often start quietly, so earlier awareness can help owners notice when an older dog needs a vet visit.

What you can do

If your senior dog seems more confused, anxious, or gets lost in familiar places, mention these changes to your veterinarian, who can discuss options and rule out other causes.
