Quick Answer: How Do Dog Years Work?

The official formula, according to the American Veterinary Medical Association, equates the first year of a medium-sized dog’s life to 15 years of a human’s.

The dog’s second year equals nine years for a human.

And after that, every year feels like five for a dog.

Is 13 old for a dog?

The aging profile of dogs varies according to their adult size (often determined by their breed): smaller dogs often live over 15–16 years, medium and large size dogs typically 10 to 13 years, and some giant dog breeds such as mastiffs, often only 7 to 8 years.

How many years are dogs to humans?

According to the American Veterinary Medical Association: The first year of a medium-sized dog’s life is 15 years of a human’s life. The second year of a dog’s life equals about nine years for a human. And after that, very human year equals approximately five years for a dog.

How do you calculate dog years?

As a general guideline, though, the American Veterinary Medical Association breaks it down like this:

  • 15 human years equals the first year of a medium-sized dog’s life.
  • Year two for a dog equals about nine years for a human.
  • And after that, each human year would be approximately five years for a dog.
