How Old is my Dog? Understanding the Timeline of a Dog’s Life

They say every year in dog years is equal to 7 in human ones, so calculating your dog’s age should be simple, right? But it turns out it’s not as simple as that.

Dogs don’t age in a linear fashion, so it’s not as easy as taking your dog’s years on earth and multiplying by 7. So now you’re thinking: how old is my dog? Keep reading and we’ll tell you how to figure out Fido’s real age.

How Old Is My Dog?

The age of your dog depends on a few factors. First is their size; bigger breeds tend to have shorter lifespans, so they’ll become seniors much earlier than smaller breeds.

Second is the stage of life your dog’s in. For instance, they’ll age much quicker in the first few years of their lives and the rate of aging will slow down after 2 years.

Below, we’ll give you a rule of thumb for calculating your dog’s age.

Year 1

The first year of your dog’s life will be the time of most rapid growth. At the end of this year, they’re about 15 years old in human years.

Year 2

The second-year will also be one with rapid growth, but not as much as year 1. In the second year, they age about 9 human years, so they’ll be around 24 in human years.

Year 3 and Beyond

After your dog turns 3, calculations should be easier. Instead of a 7:1 ratio like we initially thought, it’s a 5:1 ratio. So your dog is 15 in year 1, 24 in year 2, 29 in year 3, 34 in year 4, and so on and so forth.
