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.
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.
