In the past is was said that one dog year equals to seven human years. Today Veterinarians have come up with a more realistic comparison.

Because dogs are able to reproduce at age one and children at age seven are far from the ability to reproduce, the new age comparison came about:

This is another way to look at how old your dog is in human years.

 

Dog Years

5 Months
8 Months
10 Months
12 Months
18 Months
2 Years
3 Years
 

Human Years

10 Years
13 Years
14 Years
15 Years
20 Years
24 Years
 
 

 

After two years, the scale goes up in a ratio of four dog years for every one human year. For example: three dog years is equal to a 28 year old human then four dog years is equal to a 32 year old human and etc.

 

Below is a dog to human years chart that extends many more years.
