In a groundbreaking veterinary development that could change the future of pet care, researchers are testing a promising new medication designed to extend the healthy lifespan of dogs. The study, called the STAY trial, is the largest of its kind and has just reached a major milestone: over 1,000 dogs enrolled.
A Beef-Flavoured Pill That Targets Dog Aging
The medication, named LOY-002, is a daily beef-flavored pill currently being trialled by U.S. biotech company Loyal. It targets a key hormone called IGF-1—which is known to influence aging, particularly in large breed dogs. Larger breeds like Great Danes often have up to 28 times more IGF-1 than smaller dogs, which may explain their shorter lifespans.
By reducing the overproduction of this hormone, LOY-002 aims to delay age-related diseases, improve vitality, and extend the number of healthy, active years dogs enjoy—without simply prolonging frailty.
What This Means for Dogs Like Leo and Holy
At Chrysidis Pet Care in Gateshead, we understand just how heartbreaking it can be to watch our dogs slow down with age. Our own resident Labrador, Holy, is a living example of how dogs thrive on consistency, comfort, and routine. For dogs like Holy and our beloved guests—especially seniors and rescues—this kind of advancement offers real hope.
Imagine giving your dog a few more good years of cuddles, walks, and tail wags. That’s the potential of LOY-002.
FDA Progress and Growing Momentum
In February 2025, the U.S. FDA granted LOY-002 “reasonable expectation of effectiveness” status—a huge step forward in the regulatory process. A similar drug, LOY-001, was previously developed specifically for large-breed dogs prone to early aging.
Pet owners participating in the clinical trial have already reported noticeable increases in energy and mobility in their senior dogs. While final results are still pending due to the double-blind trial structure, early signs are incredibly encouraging.
Why Pet Longevity Matters—Especially for Anxious and Rescue Dogs
At Chrysidis Pet Care, we specialize in anxious and rescue dogs, many of whom need extra time and trust to settle into a new home. Longer, healthier lifespans could mean:
More years for dogs to enjoy a calm, stable routine. Better recovery and healing after trauma or neglect. More time for owners to bond and create lasting memories.
Our home-based, crate-free environment is ideal for older dogs who need daily medication or a slow, gentle pace. If a treatment like LOY-002 becomes available in the UK, it could further support our mission: to offer personalised pet care that prioritizes comfort and wellbeing.
Final Thoughts: A Healthier Future for Our Four-Legged Friends
This potential leap in veterinary science highlights just how important innovation is for our dogs’ futures. While LOY-002 is still in testing, its early success suggests a time may come when a longer, healthier life is the new norm for our pets—not the exception.
And until then? At Chrysidis Pet Care, we’ll continue doing what we do best—caring for every dog as if they were our own.
