How many years is one dog year to a humans if its a boxer pit mix and how long does it live in dog years?

They say 7 humans years to 1 dog year so for example if your dog is 1 year old it's 7 in human years. If your dog is 2 years old it's 14 in human years, etc etc etc... However, the conversion is only approximate, and doesn't work well for older dogs.

Boxer dogs live between 10-12 years on average and Pitt bulls between 12-15 years on average so anywhere between 10-15 years.
