As everyone knows, one year of a dog’s life is equal to seven years of a human. If this is the method to calculate how old is my dog? However, this is the not right method to calculate the dog’s age. Don’t worry! We provide the best solution in this regard as we suggest you use this dog year calculator.
In history, the method of “one dog year equals seven human years” simply shows that dogs age faster than humans, which were created by ancient people.
Unfortunately, there is no one simple formula for dog age calculation that allows you to convert dog years to human years quickly. With the passage of time, the researchers studied human and dog DNA changes called methyl groups in humans and Labrador Retrievers. After that, they concluded dogs age in human years by the given formula:
(human_age = 16ln(dog_age) + 31)
From the above formula, we can say that the first year of a dog’s life is equal to 15 years of a human to dog years. But it is remembered that one year is only like 4 or 5 humans for older dogs.
However, the second thing is that small breeds tend to live longer. Generally, dog breeds have been divided into three types and their age increases at different speeds.
Our dog age calculator calculates the age of dogs below 20 years old. As we know, the older dogs have made the Guinness World Records, but they were exceptions. On the other hand, regular dogs don’t live that long.
Here’s how old is a dog in human years compared with human age. Note that this dog age calculator is for the every-size breed of a dog below 20 years. Consult the chart to see the difference between various sizes of dogs,

As you can see above our dog age chart, the age of the small, medium, and large dogs are pretty similar when they reach the age of six. Keep in mind that larger dogs years in humans become much faster old as compared to the smaller and medium dogs.

The relationship between body mass and life longing of dogs is particularly complex and not fully understood. Nonetheless, current studies indicate that a dog’s life expectancy is decreased by 1 month for every 2 kilograms of body mass. The reason is not found for this but there are some evidence-based and objective options:
