Convert your dog’s age to human years using the 2020 epigenetic formula or the size-adjusted classic method.
Understanding the dog age calculation
The old rule of multiplying by seven was never accurate. Dogs mature far faster in their first two years and then age more slowly, and larger breeds age faster than small ones throughout.
A 2020 study comparing DNA methylation in dogs and humans produced a logarithmic formula that matches the biology much more closely, particularly for young dogs. Both methods are shown so you can compare.
Try it with these numbers
Take the starting scenario, a method of Epigenetic formula (2020 research). That gives a human age equivalent of 56.8. Underneath, Epigenetic estimate comes out at 56.8 human years and Size-adjusted estimate at 39 human years. Change any field and every figure updates as you type.
Getting your answer
- Enter your dog’s age in years.
- Select the size category.
- Choose the epigenetic or size-adjusted method.
