Dog Age Calculator

Convert your dog’s age to human years using the latest vet-based calculation methods.




How Dog to Human Years Works

Dogs mature quickly in their first two years. A 1-year-old dog is like a teenager, and by age 2, they’re more like a 25-year-old human. After that, each dog year is roughly 4 human years.

Different Breeds, Different Rates

Large breeds tend to age faster, while smaller dogs live longer on average. This calculator gives a general estimate.
