How Old is 14 in Dog Years?

14 in dog years roughly equals 78 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 14 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

Many people believe that 1 dog year equals seven dog years. This belief probably started in the 1950s, however it’s not the correct way to calculate it.

Although there’s been a lot of research since then that disproves that the ratio is 7-1, it seems that people still believe in it. The formula could be based on an assumption that dogs live to 10 or so years, and humans live can live to 70, however it’s hard to tell when it first started.

The 7 to 1 rule is easy to understand and keep in mind but it’s not the best idea.

The correct formula

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

The American Veterinary Medical Association has the following things to be said about it:

  • The beginning year of a medium-sized dog’s lifespan equals around 15 human years.
  • The second year of a dog’s existence equals about 9 human years.
  • From then on each human year is equal to 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.

She then shortlists the most common ones, and turns them into blog posts for Fuzzy Rescue. She's had over 4 cats and 2 dogs over the past decade, so she does know a thing or 2 about raising/training, and more importantly, loving them. She's the only one on our team that doesn't like coffee, but it seems to us she really doesn't need more energy :). We're very fortunate to have her on board as she does most of the heavy listing for the site, outputting an insane amount of content each month. Read More
