A very popular urban legend around the canine world assures us that one year of a dog’s existence is equivalent to seven years in human age. This is not exactly the case; this calculation lacks a scientific basis beyond being a popular method to make an approximate guess.

Firstly, not all breeds live the same years or have the same characteristics, and secondly, there are many issues and variables that influence the years of life of a dog and the aging process.

To learn how to accurately calculate a dog’s age in human years, you need to follow some basic steps that we break down below, all based on a high-impact scientific study that we analyze in detail.

Human ages and dog life: the epigenetic clock 

A team of researchers, scientists, and experts in the canine world managed to find a formula that makes it possible to calculate the age of dogs at human age accurately and based on empirical criteria (based on DNA).

Their work was collected in the American scientific magazine Science, which echoed the investigations of this team of scholars from the University of California, in the United States, who investigated the aging and evolution of dogs for months, analyzing the DNA of the different races and establishing a concept called epigenetic clock.

This watch is painstakingly designed around the different variables that we encounter in the lives of our furry friends. They are the following:

  • Weight and size of the puppy.
  • The most common diseases and their possible impact on different races.
  • The lifestyles.
  • The normal habitat of the dog type.
  • The characteristics of each breed.

The epigenetic clock seeks to offer owners an age calculation as if the dog were a person. To determine this clock, a DNA sample from 104 dogs of different breeds, whose ages ranged from one month old to 16 years old, was analyzed.

The researchers estimated that certain genetic chains (that operate during evolutionary development) are methylated in a similar way during aging in humans and dogs, i.e., that they share evolutionary tendencies typical of mammals. In other words, dogs evolve in a similar way to humans.

In general, the epigenetic clock of dogs advances at a high, dizzying rate, much faster than that of humans. But, as it progresses, it slows down and approaches, in a natural way, the rhythm of the people.

Steps to calculate the age of small dogs or large dogs

Classify the dog in one of the following subgroups:
The first step to calculating the human age of our furry dog is to choose one of the following groups based on his body weight:

  • Weight is less than 15 kilograms = small breeds.
  • The weight ranges from 15 to 40 kilograms = medium breeds.
  • Weight exceeds 40 kilograms = large breeds.

How to know the age of a dog? What is 7 years in the age of a dog?

There are several rumors. The most common is the multiple by 7 and its variables, and then the scientific method. In this article, we will analyze both cases.

The table to calculate the dog’s age in human age

To calculate your pet’s age, consider that a puppy ages 15 times faster than a human in its first year, and then add 6 years in its second. Next, add about 4 years for each additional year to get your dog’s age in human years.

The following table helps you calculate your dog’s age:

The scientific calculation of the real age of dogs in human age

Once the type of breed has been determined, we have to look in our drawer and use the scientific calculator. If we do not have one, we can use an online calculator, with which we can carry out the mathematical calculation of the logarithm in question.
The formula developed by North American researchers to determine the human age of the dog would be the following (provided that the dog has been at least one year old): multiply the logarithm of the dog’s chronological age by 16; to this result, we must add 31. The result would give us the real age of our furry friend in human terms.

A very basic example: a medium-breed dog that is 2 years old in its dog age is equivalent, according to this age calculator, to 42 years in its human age version. Another example is that a cute 7-week-old puppy would be paired with a 9-month-old human baby, an age when both are teething.

What is the purpose of calculating the human age of the dog?

Knowing a dog’s human age, rather than its biological age, helps us empathize with our pet. This way, we know what his life expectancy is and when we should do it. Medical reviews, what their vital status is, understand them better, know if they are more tired, etc. Many times, owners create better bonds with the dog when they can make this parallel.

The focus study of this article was carried out with several scientific objectives, but one of the main intentions was to compare the different breeds of dogs and study their epigenetic profiles to find out why some dogs have a greater life expectancy than others and also to study certain diseases that affect different breeds of dogs.

Dog behavior changes with age

Furthermore, a recent study on dog behavior carried out by William J. Chopik and Jonathan R. Weaverque from the University of Michigan concluded that dogs learn things, mutate, refine their personalities, and change their way of relating to others. world as time passes and we tear through the pages of the calendar. It is not something exclusive to them; this malleability of the inner being is also typical of human beings.

In addition to the relationship with the years of life, the study argued that the personality of the dog is closely linked to that of its owners. In this way, the most active, happy, and open dogs are those of the most extroverted owners, and vice versa, the most introverted and calm dogs correspond to the most reserved and homely owners.
