How Old is 1 month in Dog Years?

Last Updated on September 20, 2023

1 month in dog years roughly equals 7 months in human years.

This calculation was made for a medium-sized dog (21 to 50 pounds) using the recommendations from the AKC (American Kennel Club).

There are 2 ways of calculating the conversion from human years to dog years. The above result was calculated using the more correct way, we’ll explain what makes the other way incorrect later in this article.

The table below shows dog years and their equivalent to human years, with different columns for different sizes.

Calculating how many human years is 1 month in dog years

As mentioned above, there are 2 main ways of calculating dog years to human years and vice versa. There’s a correct way and an incorrect way.

The incorrect calculation

Most people still assume that one dog year equals seven dog years; this assumption was probably first introduced in the 1950s, however this isn’t the best method of calculating it.

While there has been quite a bit of research since then that disproves that the ratio is 7-1, people are still holding on the idea. This formula might have been based on the idea that dogs live to 10-ish years and humans to 70, but honestly it’s hard to tell when it first started.

Therefore, while the 7-1 rule is simple to understand and keep in mind, it’s unfortunately incorrect.

The correct formula

The proper method to convert human years to dog years is more difficult.

The American Veterinary Medical Association has the following to add to it:

  • The very first year of a dog’s life equals around 15 human years.
  • The second year of a dog’s life equals about 9 human years.
  • From then on, every human year equals either four or five dogs years.

Keep in mind that smaller dogs tend to live longer than bigger dogs. Scientists concluded that every 4.4 pounds of body mass reduced a dog’s life expectancy by about a month.
