Doggy Years: Chances Are You Miscalculated Your Dog’s Age

As a dog owner, you have probably heard the rule of thumb that one dog year is equivalent to seven human years. Calculating your furbaby’s age shows to be more involved that one may have realized.

The truth reveals the 7-year multiplication rule is FALSE and that the math is not that simple. 

Dogs mature a lot faster than humans do in the early growth years. In fact, the first year of a pup equals about 15 human years.

Dogs are the most diverse mammal species on the planet. They can vary in weight from 6 lb. to 200 lb. When fully grown, dogs possess a widely differing body shapes and hair types.

This also means that there is a lot of variation among breeds in terms of life expectancy.

Size and Breed Matters

Depending on the size and breed of dog, the lifespan can be shorter or longer. Typically, smaller dogs live longer than larger dogs however smaller dogs mature faster in the first few years of their life. On the other hand, a large dog ages slower in the beginning, but is reaching middle-age when the dog is only five years old. Tiny or toy breeds don’t become “seniors” until about ten years.

Since dogs age faster in the first two years, they can reach sexual maturity after one year for reproduction.
