MyPetCalculator was built for one simple reason. Most pet age and health tools online are either inaccurate, outdated, or impossible to use on a phone.
We use science-backed formulas including the UC San Diego epigenetic research, AVMA guidelines, and AKC breed data to give pet owners accurate, instant answers, free and with no signup required.
Our calculators cover dogs, cats, horses, rabbits, hamsters and birds. Every tool is checked against published veterinary guidelines before it goes live. The calculators are not written or reviewed by a veterinarian.
MyPetCalculator is not a veterinary service. We’re pet owners who believe better information leads to better care. Always consult your vet for medical decisions.
