Some dogs get more than 15 years with us.

Some only get 7 or 8.

They all deserve more time. What if we could give it to them?

Loyal is a clinical-stage veterinary medicine company.

We’re developing drugs intended to delay and reverse aging in dogs, because we believe they deserve as many happy years as we can give them.

Our mission is to improve your dog’s healthspan (quality of life) and lifespan (years of life).

Loyal is backed by decades of research on the biology of aging.

We need dog owners’ help to make this happen.

Slow aging, delay disease.

By developing drugs with the potential to slow the aging process, we aim to delay or prevent age-related diseases like cancer and dementia.

Our goal is to give our dogs more healthy and happy years.
