How Old Is Your Pet in Human Years?
Forget the outdated "7 years" rule. Our breed-specific calculators use veterinary research to accurately convert your pet's age to human years.
Calculating your pet's age in human years isn't as simple as the old "7 years per dog year" rule. Different breeds age at dramatically different rates — a Great Dane reaches senior status at age 5, while a Chihuahua may not be considered senior until age 11. Our breed-specific age calculators use the latest veterinary research to give you accurate results for over 30 dog and cat breeds. Simply select your pet's breed below to discover their true biological age and life stage.
