It is often said that a dog's year is equal to seven human years - but is it?

Use this chart to check your dog's age. You will see that the 7:1 ratio is only a very rough guide, and that after the age of 2, the comparative human age changes significantly dependant upon the size of your dog.

We do not claim this chart is necessarily accurate, but it is a good guide, and a good bit of harmless fun!

The age of your dog is shown in green, with the human age shown in the outer colours.

Up to the age of 2, all sizes "age" the same.
