Clinical Development Veterinarian

About Loyal

Loyal is a clinical-stage veterinary medicine company developing longevity drugs for dogs. Our mission is to help dogs live longer, healthier lives.

We're pioneering a new category of veterinary prescription drugs that proactively and preventatively target the underlying drivers of aging, delaying the onset of disease and preserving quality of life as dogs age. We've already made significant progress in our mission to develop the first FDA-approved drugs to extend canine lifespan: as of early 2026 we've completed two of three major FDA review sections for our lead program, LOY-002, and are targeting submission of the third and final section later this year.

Loyal is a well-funded startup with teams of scientists, veterinarians, engineers, operators, and creatives. You'll help us continue on our path of earning FDA approval for the first lifespan extension medicine for any species — and change what's possible for the dogs we love.
