Clinical trials have begun for the first anti-aging pill for dogs, aiming to extend their lives by at least an extra year. The trials could ultimately pave the way for similar drugs for humans.

The research will involve 1,000 dogs older than ten years old, monitored over four years to assess lifespan and quality of life improvements.

Loyal, the San Francisco startup behind the pill, is seeking FDA approval for a chewable version and an injectable alternative for large dogs, with a target of early 2025 for approval.

Researchers have discovered that dogs experience similar environmental conditions to humans and appear to have similar age-related dynamics with disease risk, allowing them to serve as a model for longevity.
