A recent study from North Carolina State University suggests that slower walking in dogs could signal cognitive changes similar to dementia in people. The work, published in Frontiers in Veterinary Science, adds to a growing body of evidence linking mobility and brain health in canines.
In humans, a drop in walking speed often tracks cognitive aging. Researchers wondered if the same pattern might appear in dogs. They designed a series of tests that tracked how fast dogs walked, both when on a leash and when they moved freely, to determine which setting offered clearer clues about brain function.
The project involved a group of 46 adult dogs and 49 senior dogs. Walking speed was recorded for the adult dogs, while the senior dogs also underwent assessments of their cognitive abilities. By comparing these groups, the team aimed to identify any consistent relationship between pace and mental processing in aging dogs.
One challenge noted by the investigators is that dogs tend to adjust to their owner
ash;s pace when leashed. To address this, the researchers measured speed in two scenarios — with and without the leash — to determine which measure most accurately reflected the animaldash;s natural tempo and cognitive status.
Across the study, older dogs generally moved more slowly than younger ones, a result that held even after accounting for body size. Importantly, slower speed correlated with greater signs of cognitive decline in the senior group, suggesting a potential link between movement and brain health in aging dogs.
The researchers described walking speed as a potential quick screening tool that veterinarians could use during routine exams. Such a test would be simple to perform and could help identify dogs that might benefit from further cognitive evaluation or supportive interventions.
Notably, the study excluded dogs with significant osteoarthritis, ensuring that joint pain did not confound the observed link between pace and cognition. The findings imply that mobility is partly governed by how the brain processes information, and that changes in movement may reflect underlying cognitive shifts.
As activity levels decline, the nervous system receives less input, which can influence both motor control and cognitive processing. The study authors emphasized that a measurable drop in walking speed could align with emerging signs of dementia in dogs, offering veterinarians a simple, noninvasive screening approach for canine brain health.
The researchers also highlighted that aging dogs, like their human counterparts, may show variability in how quickly they respond to environmental cues, process information, and adapt to new tasks. These factors collectively influence gait and overall mobility, reinforcing the idea that movement is a window into brain function.
In practical terms, veterinarians could integrate a short walking-speed assessment into routine checkups, using it alongside other observations of behavior and cognitive function to form a more complete picture of a dogdash;s mental health. Early identification of cognitive changes is valuable because it can guide care decisions, environmental enrichment, and management strategies that support quality of life for older dogs.
Ultimately, the study underscores a broader concept: the brain, nerves, and movement are tightly linked. When cognitive processing slows, the pace at which a dog moves may slow as well, even if physical capabilities remain intact. This evolving understanding helps owners and clinicians approach aging dogs with a more nuanced view of mobility, mood, and mental sharpness, offering practical steps to monitor and support canine brain health.
These findings contribute to ongoing discussions about noninvasive ways to screen for cognitive changes in dogs and remind caregivers that changes in daily activities can reflect deeper brain processes. By paying closer attention to how fast a dog walks, owners may gain early insight into cognitive shifts, enabling timely conversations with veterinarians about care planning and supportive therapies.
