Pet Age to Human Years Calculator (Dogs & Cats)

Is your dog actually 7 times older than you in "dog years"? Not quite! Our Pet Age Calculator uses the latest non-linear biological formulas to convert your cat or dog's age into equivalent human years.

Young pets age much faster in their first two years. For example, a 1-year-old dog is roughly equivalent to a 15-year-old human. After the age of two, the aging process stabilizes. This tool helps you understand your pet's life stageโ€”whether they are a junior, adult, or senior.

Pet Aging FAQ

Is the 1-year = 7-years rule accurate?

No, that is a common myth. Real aging is non-linear; pets mature very quickly in their first 24 months.

Do different dog breeds age differently?

Yes. Large breeds typically age faster than small breeds. Our calculator uses a general average for precision.

When is a pet considered a 'Senior'?

Usually, when their human-equivalent age passes 50-60 years, varying by species.
