A new study published in the journal Frontiers in Veterinary Science examined 88 senior dogs to determine whether the way they walk is linked to age-related changes in the brain.
The dogs underwent both physical and neurological examinations, while their owners answered questions about their behavior and cognitive health.
Researchers also measured the dogs’ stride length and walking speed as they walked at their normal pace over a short distance, according to HealthDay.
Several factors may be involved
The study found that changes in a dog’s gait are not always caused by problems in the brain.

Pain caused by conditions such as arthritis or neck disorders can also affect the dog's movement.
For that reason, the researchers recommend that dog owners have their pets examined by a veterinarian if they notice any changes in the way they walk.
Although there is currently no cure for canine dementia, the researchers say that an early diagnosis may allow owners to adapt their dog’s daily routine and improve the animal's quality of life.
Stride length
The study found that the dogs’ front-leg stride length became shorter as their cognitive function declined.

This association was stronger than the changes that could be explained by aging alone.
The researchers did not observe the same pattern in the hind legs. They therefore conclude that a shorter front-leg stride may be an early indicator of dementia in older dogs.
