How the Dog Aging Project is working to extend your dog’s life — and yours too

Since it began in 2018, the Dog Aging Project has gathered data on more than 50,000 dogs in the effort to better understand how quickly they age and, potentially, prolong their lives.

In the study, researchers made a distinction between a dog’s life span — the total number of years lived — and a dog’s healthspan — the total number of years lived in good health. Their goal was to maximize the quality of a dog’s health, not just simply extend their lifespan.
