A biotech company called Loyal has developed a drug that might help dogs live longer. The drug, named LOY-002, works by copying the benefits of eating less food, which scientists know can extend life in many animals.
The FDA’s Center for Veterinary Medicine has already accepted part of the approval process for this drug, specifically the “Reasonable Expectation of Effectiveness” section. This means the drug has shown promising early results.
The Science Behind Dog Aging
Loyal’s approach targets the basic processes of aging in dogs. By mimicking caloric restriction—eating fewer calories while still getting proper nutrition—the drug aims to slow down aging at the cellular level.
This matters because different dog breeds age at different rates. Small breeds like Chihuahuas typically live 12-20 years, while larger breeds like Great Danes often only live 6-8 years. A drug that addresses aging directly could benefit all dogs, especially larger breeds with shorter lifespans.
Largest Dog Study Ever
To prove their drug works, Loyal is running the STAY study—the largest veterinary clinical trial in history. This multi-year trial involves more than 1,000 senior dogs across various veterinary clinics in the United States.
The study isn’t just looking at how long dogs live but also how well they live as they age. Researchers are tracking improvements in energy levels, brain function, and movement—all things that decline as dogs get older.

Beyond Extending Life
Celine Halioua, Loyal’s CEO, has emphasized that their goal isn’t just to make dogs live longer but to improve their quality of life in their later years. This means healthier, more active senior dogs who can enjoy life with their families for longer.
If the FDA grants conditional approval, dog owners might see this drug on the market as early as next year.
What This Means for Human Longevity
Dogs share many age-related health problems with humans, including arthritis, memory loss, and heart issues. This makes them excellent subjects for studying aging.
Success with LOY-002 could speed up the development of similar drugs for humans. Scientists see dog studies as a steppingstone to human longevity research since dogs age faster than humans but live in the same environments.
Growing Industry Interest
Loyal has raised significant funding for their research, including $22 million in their most recent round. This shows strong investor confidence in pet health technology.
The pet care industry has been growing steadily as more people view pets as family members and seek advanced healthcare options for them. A successful longevity drug would create a new market within pet healthcare and might encourage more companies to develop similar products.
FAQ Section
Frequently Asked Questions
What is LOY-002 and how does it work?
LOY-002 is a drug developed by Loyal that aims to extend dogs’ lifespans by mimicking the benefits of caloric restriction (eating less food while maintaining proper nutrition). This approach targets the fundamental processes of aging at the cellular level, potentially slowing down the aging process in dogs. Rather than treating specific age-related diseases, it addresses the underlying biological mechanisms of aging.
When will this drug be available for my dog?
If the FDA grants conditional approval, LOY-002 could be available on the market as early as next year. The drug has already received acceptance for the “Reasonable Expectation of Effectiveness” section of the FDA approval process, which is a promising step toward full approval. However, the exact timeline depends on the results of ongoing clinical trials and the complete FDA review process.
How much longer could my dog live with this drug?
While specific lifespan extension numbers haven’t been publicly shared yet, the drug aims to address the biological processes of aging, which could be particularly beneficial for larger dog breeds that typically have shorter lifespans (6-8 years) compared to smaller breeds (12-20 years). The focus is not just on extending lifespan but also on improving quality of life during a dog’s senior years, including better energy levels, brain function, and mobility.
Is this drug safe for all dogs?
The ongoing STAY clinical trial—the largest veterinary clinical trial in history with over 1,000 senior dogs—is designed to evaluate both the effectiveness and safety of LOY-002. As with any medication, safety profiles may vary depending on a dog’s age, breed, size, and existing health conditions. Full safety information should become available after the trial concludes and the FDA completes its review process.
How much will the treatment cost?
Pricing information for LOY-002 has not yet been released. As a novel treatment targeting aging itself rather than specific diseases, it represents a new category of pet medication. Loyal has raised significant funding ($22 million in their most recent round), indicating substantial investment in developing this technology, but the final consumer price point will likely be determined closer to market release.
Could this lead to similar treatments for humans?
Yes, success with LOY-002 could accelerate the development of similar drugs for humans. Dogs make excellent subjects for aging research because they share many age-related health problems with humans (arthritis, memory loss, heart issues) but age more rapidly while living in the same environments. Scientists view dog studies as valuable stepping stones to human longevity research, and breakthroughs in canine longevity could provide valuable data and proof-of-concept for human applications.
