Scientists have created a pill that could help your dog live for years longer

Your Dog’s Life Could Be Extended by New Daily Pill: What to Know

A new daily pill being developed by veterinary scientists could help senior dogs live longer.

The treatment, which is still under regulatory review, is designed to slow the biological aging process in dogs and may become the first FDA‑approved drug to explicitly extend a pet’s lifespan, according to early testing from San Francisco-based biotech company Loyal.

Why It Matters

For millions of dog owners, aging often brings chronic illness, declining mobility, and difficult end‑of‑life decisions. A pill designed to slow aging itself, rather than treat individual diseases, could represent a fundamental shift in how veterinarians approach senior pet care.

The drug could be especially significant for medium- and large-breed dogs, which typically live shorter lives and experience faster biological aging linked to higher levels of the hormone IGF‑1. By targeting that process, researchers say the treatment may extend not just lifespan but also the number of healthy years lived.

What To Know

The drug, known as LOY‑002, is being developed by Loyal and works as a beef‑flavored prescription pill intended for dogs aged 10 and older who weigh more than 14 pounds, Good.is reported.

Rather than treating a specific disease, LOY‑002 targets aging itself by interacting with insulin‑like growth factor 1 (IGF‑1), which is a hormone involved in growth and metabolism. While IGF‑1 helps puppies grow, higher levels of the hormone later in life are associated with faster cellular aging, especially in larger dog breeds. 

By reducing the effects of IGF‑1, the pill aims to slow a dog’s biological clock, potentially lowering the risk of age‑related disease and extending overall lifespan while preserving quality of life. 

The drug may be particularly beneficial for medium- and large-breed dogs, which tend to live shorter lives than smaller dogs. Larger breeds generally have higher IGF‑1 activity, which scientists believe accelerates aging and increases vulnerability to organ dysfunction later in life.
