Research to help dogs live longer, healthier lives could unlock secrets for people to age better, too

TL;DR

  • The Dog Aging Project studies over 50,000 dogs to understand aging and age-related diseases, which are similar to human conditions like dementia.
  • Dogs serve as a valuable intermediate model for studying diseases and treatments, as they share environments and biology with humans, and age faster.
  • Research has shown correlations between lifestyle factors and disease risk in dogs, such as fewer diseases in dogs living with other dogs and a higher risk of dementia in inactive dogs.
  • Studies are testing drugs like rapamycin, which has shown potential in slowing cognitive decline and reducing inflammation linked to dementia in canine trials.
  • Biotech companies are developing drugs for dogs with the goal of extending healthier lifespans, with the long-term vision of applying similar research to human longevity.
