How Old Is My Dog?

They might be your “baby,” but they’re still growing up.

Let’s find an answer to the question, “How old is my dog?”


If you’ve ever owned a dog, you’ve probably noticed that they age a lot differently than humans do.

Three weeks after birth, puppies are alert, active, and trying to climb over everything in sight. A three-week-old infant, on the other hand, still sleeps for much of the day.

These differences ultimately come down to human and dog DNA, but it can also make it difficult to determine how old your dog is in human years.

You may have heard that calculating dog years to human years is as simple as multiplying two numbers, but the answer is a bit more complicated.

Luckily, we’ve put together an age chart for dogs that breaks it down for you.
