Is 1 Dog Year Really 7 Human Years?

For a long time, the common rule of thumb was that one dog year equals seven human years. However, veterinary science has proven this is a myth. Dogs mature much faster than humans in their first two years of life.

Our Dog Age Calculator uses the latest veterinary guidelines established by the American Veterinary Medical Association (AVMA). It factors in the size of your dog (small, medium, large, or giant), because larger breeds age faster in their senior years compared to smaller dogs. Just enter your dog's age to find out how old they truly are in human years!
