How Old is 2 in Dog Years?

2 in dog years roughly equals 24 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 2 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 old calculation

The majority of people still believe that 1 dog year equals 7 dog years. This assumption was probably first introduced in the 1950s, however it’s not the right way to calculate it.

There has been plenty of research that has disproved the 7:1 ratio, that people still believe in the idea. The formula could be based on the belief that dogs live for 10 or so years, and humans live reach 70 years old, but honestly we don’t know the date it was first introduced.

Therefore, while the 7-1 rule is simple to remember and calculate however, it’s sadly incorrect.

The correct formula

The correct way of converting human years into dog years is a bit more complicated.

The American Veterinary Medical Association has the following to say about it::

  • The beginning year of a medium-sized dog’s life is approximately 15 years human.
  • The second year in a dog’s lifespan is roughly 9 years for humans.
  • From that point forward, every human year equals four or five dog 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.
