More good years. Together.

Dogs are living longer than ever. But the years that matter most are the good ones: the greeting at the door, the long walk, the spark when they hear your voice.

Leap Years was built for those years. Not just more time with your dog. Better time.

VMD, DACVIM Chief Veterinary Medical Officer & CEO

A board-certified veterinary internal medicine specialist with more than 30 years of clinical and pre-clinical experience, Dr. Rentko has one mission: help dogs stay healthy for more of their lives, starting where aging starts, inside the cell.

Under her guidance, Leap Years was developed at Animal Biosciences, co-founded by Harvard geneticist Dr. David Sinclair, and tested in a randomized, placebo-controlled trial at the NC State College of Veterinary Medicine.
