Have you ever wondered how old your dog is in human years? You can find out by using the chart below to figure it out. Just find your dogs age ( how old he is now) and look to the right to see how old he would be as a human.
*sources differ on the later years
This chart is based on tooth and bone growth, sexual maturity and other factors related to maturity. It is not exact but is a good comparison. Larger breeds of dogs have a shorter life span than smaller dogs, and a small dog may mature more quickly in the first few years than a large dog would.
