Pet age calculator

How old is your dog or cat really, in human years? Uses the real size-adjusted veterinary guideline, not the ×7 myth.

In human years

34

Your pet is about 4 dog years old — roughly 34 in human years.

Uses the size-adjusted guideline published by the AVMA and AKC: year one ≈ 15 human years, year two adds 9 more, then each year after adds 4–7 depending on size — not the old ×7 rule. More on how we source guidance.
