Dog Age Calculator
Convert your dog's age into human years with a more accurate modern formula.
Convert your dog's age into human years using a more realistic curve than the old "multiply by seven" myth. Dogs mature fast in their first two years, then slow down, so a one-year-old dog is roughly a 15-year-old human. Enter your dog's age for an estimate — actual ageing varies by breed and size.
Frequently asked questions
Is one dog year really seven human years?
No, that is a myth. Dogs age quickly early on: a one-year-old dog is about 15 in human terms, and a two-year-old about 24.
How do I calculate my dog's human age?
Enter your dog's age in years; the tool applies a realistic curve rather than a flat multiplier.
Does breed affect ageing?
Yes, smaller dogs generally age more slowly later in life, while large and giant breeds age faster.
Is the result exact?
It is an approximation for fun and general guidance; your vet is the real authority on your dog's health.
