Study Tracks 1.2% Shorter Dog Front-Leg Strides to Cognitive Decline in 88 Seniors

Summary
Eighty-eight senior dogs in a North Carolina State study showed progressively shorter front-leg strides as cognitive impairment worsened, with a 10-point rise on the Canine Dementia Scale linked to a 1.2% reduction.
A five-metre walkway test found the signal in front legs, not hind legs, suggesting higher-brain control of braking and direction changes makes forelimb movement more sensitive to dementia-related decline.
Pain and orthopedic problems also shortened stride, but the cognition link held after researchers accounted for them; walking speed alone was less informative than stride-length measurements.
The team said the measure is not a standalone diagnosis, but repeated tracking could help vets spot canine cognitive dysfunction earlier and start lifestyle interventions such as enrichment, diet and routine.
