We’ve Been Calculating Dogs’ Human Age All Wrong

People have calculated dog’s human age by multiplying their age by seven. So if a dog is three years old, then we’d say it was 21 in human years. But, according to scientists, we’ve been calculating dogs’ human age all wrong all along.

It’s been recently revealed by scientists that a dog’s human age, according to a study that involved 100 Labrador Retrievers, that a one-year-old puppy is actually the equivalent of a 30-year-old human!

That makes more sense than calculating a nine-month-old puppy as a 5-year-old in human years because a puppy of this age can reproduce.

So, it’s believed that in the first few years of a dog’s life, it “ages” in human years much faster. A two-year-old dog is considered 40 years old in human years and a four-year-old pooch is about 50 years old.

According to this study, by the time the dog turns seven, its age really begins to slow down, as can be seen in the chart below, the curve flattens.

Let’s wait and see what further studies will uncover about correctly calculating dogs’ human age.
