Dog Age Calculator

Why "multiply by 7" isn't accurate

Dogs mature much faster than humans in their first couple of years, then age more slowly afterward — a flat "1 dog year = 7 human years" doesn't reflect that curve. This calculator instead uses a logarithmic approximation that better matches how dogs actually age: fast early maturity, slowing down over time.

Keep in mind this is still a general approximation — a dog's breed, size, and individual health all affect their actual aging rate. Larger breeds tend to age faster in their senior years than smaller breeds. For anything specific to your dog's health, a vet is always the better source.
