The Truth Behind How Old Is a Dog in Human Years

For as long as you can remember, there's always been a distinction between the age of a dog in "dog years" versus that of human years.

Are you ready to really learn how old is a dog in human years and if that really means anything? As always, we are going to shed light on another dog topic that has people talking. Keep reading to learn more.

The First Year

As much as there is an easy topic that compares the age of dogs to the age of humans, we know that it's a controversial subject. What is commonly circulated is that for every human year, there are 7 dog years in comparison. The reality is that it doesn't matter the breed, all dogs will develop and age very similar to 15 human years in their first year of life. You read that right. In the first 5 months, your pup will lose teeth and by seven months old, they will have all of their adult teeth.

The "Terrible Twos"

Once again, as in the first year, the second year of your pup's life will be the same regardless of the breed or size. They will all age pretty much at the same rate, with little variants. During the "terrible twos" your dog will age a total of 9 human years. So how old is a dog in human years? This means that after only 2 years, your dog is already past the human legal drinking age and well into their mid-20s!

Puberty Time

Small dog breeds grow much faster out of the puppy stage than larger dogs but they will eventually catch up to them. Large dogs reach middle age faster than small dogs.

40 Fine

In your dog's fifth year of living in the big world, this is when they start a little more rapidly. Small dogs weighing 20 pounds or less are approximately 40 in human years while they are only 6 in dog years. For larger dogs, add 2 more years.

Senior Dogs

If you can believe it, after only 6 years of living, your dog will technically be considered a senior dog. They will continue to age anywhere from 3 to 5 years over just 1 human year.
