Pet Age Calculator
A more realistic estimate than the old seven-year rule — adjusted for species, size, and how pets mature.
How it works
Dogs and cats mature quickly in their first two years, then age more steadily. Larger dogs tend to age faster later in life, so we adjust for size.
This calculator provides a general age estimate. Individual pets age differently depending on breed, size, genetics, health, and lifestyle. Ask your veterinarian for guidance specific to your pet.
