Pet age
Pet age in human years
Based on the common AVMA/AKC chart: 1st year = 15, 2nd year = +9, then +4–6 per year (small dogs age slower, large dogs faster).
How old would the same pet be as other animals?
Rough multipliers — for fun comparison only, since species age at very different rates.
How old is your pet in human years?
Calculate your dog's or cat's age in human years. The old 'multiply by seven' rule is a myth — pets mature fast when young and slowly later, and size matters a lot for dogs.
It answers questions like 'how old is my dog in human years', 'dog years to human years calculator' and 'how old is a 14-year-old cat?' — using the way pets actually mature rather than the old ×7 myth. Dog results adjust for breed size, because a Great Dane and a Chihuahua age very differently.
Good to know
- Dogs mature quickly in their first two years, then slow down.
- Small dogs generally live longer than large breeds.
- Cats reach roughly human adulthood within their first two years.
