How Old is Your Dog in Human Years?

How old is your dog in human years?

How old is your dog in human years?

Contrary to popular belief, one “dog year” does not equal seven human years. We see many 20-year-old dogs, but we are yet to even hear of a 140-year-old human! Along the same line, a dog that is two years old is an adult. A 14-year-old teenager is just that… a teenager.

The most accurate way to determine the relative age of your dog is to know the life expectancy of your dog’s breed. Small breeds tend to live longer, frequently 14 to 17 years or longer. Giant breeds, like Great Danes, have a life expectency that is significantly shorter. Even with that knowledge, however, there is no easy way you can determine the “People” age of your pet because of the many variables in the aging process of dogs, particularly in the first few years. It is fun to know though!

The chart shown below is a fairly accurate measure of the age of the average dog when compared to humans. The good news is that pets, like people, have a longer life expectancy today than ever before; primarily due to better healthcare and nutrition.

Great article! I always thought that 1:7 human/dog ratio was the norm….

Great article. I am planning to get a small dog (pug/basenji I hope) after i move in the spring. It would not be fair to get the dog any sooner, and then move him 500 miles. Any hints you can give me on the pug breed would be most welcome.
