Front-Leg Stride Changes Could Flag Dementia in Aging Dogs
NC State researchers analyzed 88 elderly dogs and found that front-leg stride length shortens with cognitive impairment, with the cognitive effect larger than age alone. While not a standalone diagnostic (gait can be affected by pain and other conditions), thoracic limb stride length could be an objective, scalable tool to monitor canine dementia alongside cognitive tests and veterinary exams. The study, published in Frontiers in Veterinary Science, may also inform human dementia research. If owners notice shortening strides, they should consult a vet.
