Find out how old your dog or cat would be in human years. Enter their age and species below. Different animals age at different rates, so understanding your pet's life stage can help you provide the right care.
Pets mature quickly in their early years and then age more slowly. Dogs, for example, reach adulthood around age two; after that, each dog year equates to roughly four to five human years. Cats have a similar pattern but with slightly different conversion factors. Our calculator uses veterinary guidelines to estimate your pet’s equivalent human age.
Use the result to tailor diet, exercise and health checkups to your pet’s life stage.
