The idea of extending a dog’s life has long existed between hope and heartbreak for pet owners. Dogs are companions and emotional anchors, and watching them age brings visible signs of slowing down. A new treatment, LOY-002 developed by Loyal, suggests aging may be modifiable.

Rather than viewing aging as fixed, researchers now see it as a biological process that can be studied and influenced. LOY-002 targets older dogs, especially larger breeds that age faster, aiming to extend not just lifespan but healthier, more active years.

It focuses on IGF-1, a hormone involved in growth and metabolism. While essential in youth, high levels later in life are linked to faster aging in some dogs. The treatment aims to modulate this pathway to slow age-related decline and disease progression.
