So the dog:human ageing ratios is 10.5:1 rather than 7:1. When a dog hits the three year mark, he ages 4 years to every 1 human year bringing the ratio to 4:1. So a 10 year old dog is basically the equivalent of a 53 year old human. Using the simple equation, this same 10 year old dog would be 70 years old.
