Dog Age Chart: See How Old Your Dog is in Human Years

Dog Age Chart & Calculator: Dog to Human Years

We have all heard the age old “tail” that each dog year is seven human years but is that the truth?

I was sitting at the kitchen table watching my one year old dog play with his toys. As I sat there watching him play and acting like a little kid on christmas with his new toy, I wondered how old he actually is in human years. So I decided to do some research to find out if the old myth was true.

It turns out that we have all been lied to! One dog year does not equal seven human years. In fact, the conversion is much different than 7:1.

Since dog’s age much more quickly they we do, their first year is actually equal to 15 of our years.

Around the age of 7, most dogs enter their senior stage of life. Dog’s in their senior years are more likely to develop these health issues:

  • diabetes
  • kidney disease
  • heart disease
  • cancer
  • hypothyroidism

Even though I wish our dogs could live our entire lives, the fact is they age much more quickly than we do. That’s why it’s important to give them great diet and nutrition but also a happy, healthy, and full life.
