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 consider 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 dog's second year then equals nine years for a human.

After that, the calculation is five years for a dog. (See your calculation below)

How to Calculate a Dogs Age in Human Years

The average calculation of a dog's age is broken down:

• 15 human years is the same as the first year of a medium-sized dog.
• The second year of a dog's life equals about 9 years for a human.
• The remaining years, every human year, is equal to an additional 5 years of a dog's life.

How they Calculate Dogs Age to Human Years

Bigger dogs 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, we consider them to be a "senior dog."

Bottom Line: We Love our Pets

No matter how long our pets come into our lives. The bottom line is that we love our pets, sometimes unconditionally.

As our pets age, they will need extra love and attention to ensure a wonderful quality of life. They deserve as much love, care and attention as any human being out there.

After all, they are often our most loyal and consistent companions.
