Is 1 dog year really 7 human years?

The old rule of multiplying a dog's age by 7 is actually a myth. Dogs age much faster in their first two years of life compared to humans, and then the aging process slows down.

How does size affect aging?

Small dogs tend to live longer than large dogs. While a Great Dane might be considered a senior citizen at age 7, a Chihuahua is typically still energetic and active at that age. Our calculator uses the guidelines from the American Veterinary Medical Association to give you a more precise estimate based on weight.
