Researchers at North Carolina State University enrolled 88 geriatric dogs with an average age of about 12 years. The dogs were checked roughly every six months. At each visit they had physical and neurologic exams, mobility tests, hearing checks and blood work. Dogs also completed a standard cognitive test and owners filled out questionnaires about behavior and pain.
Gait was measured as each dog walked a straight five‑metre indoor path. The team measured stride length for front and back limbs and adjusted values for dog height. They found that owner‑reported cognitive decline was associated with shorter front‑limb stride length, while back‑limb stride length showed no clear link.
