Want to figure out how old your dog really is? You can Quickly Calculate Your Dogs Age into Human Years.
Have you heard that old saying that one human year is equivalent to seven in dog years?
While that has been around since the 1970's it doesn't take into account size or weight.
The official formula according to the American Veterinary Medical Association states that the first year of a medium-sized dog's life is equal to 15 years of a human's life.
The dogs second year then equals nine years for a human.
After that the calculation is five years for a dog. (See your calculation below)

- The remaining years, every human year is equal to an additional 5 years of a dogs life.

How they Calculate Dogs Age to Human Years
Bigger dogs tend to have shorter lives, therefore they age faster.
For example, the life of a Great Dane is just eight years. Therefore a 4-year old Great Dane is already 35 years in human years.
By the time a small dog and even a cat are seven years old they are considered to be a "senior dog."
