A common question among dog owners is how old their pet is in relation to human years. It is easier to understand a dog’s needs, development, and how to care for them at different stages of life when you know how old a dog is in human terms.
Contrary to popular belief, which holds that one dog year is equivalent to seven human years, the truth is a little more nuanced. Dogs age differently from humans based on a variety of factors, including size, breed, and genetics. These factors all affect how closely a dog’s age matches ours.
This article will explain how to more precisely calculate your dog’s age in human years so that you can better prepare for your dog’s aging and maturation.

How long do different breeds live
It should be mentioned right away that a dog’s typical lifespan varies depending on its breed. Small breeds can live much longer than large breeds, which have a shorter life cycle. Great Danes, for instance, typically live 6–8 years, whereas small Chihuahuas can live up to 20 years.
But, it’s crucial to take the dog’s lifestyle into account in addition to its breed. Well-groomed dogs that get enough exercise each day and eat a healthy diet can live longer than dogs that don’t get enough love and care.
It’s also critical to keep in mind that dogs may age-related illnesses like diabetes and arthritis, which may have an impact on their level of activity and physical health.
How to calculate a dog"s age in human years?
There are a few different ways to calculate this, but the most popular one is based on the idea that a dog’s first year of life is roughly equivalent to 15–16 years of human life. Every year a dog lives after the first year is roughly equivalent to five or six years of human life.
For instance, a dog of five years old is roughly equivalent to 36–40 years old in human years.
Therefore, it’s not as simple as it might seem to estimate a dog’s age based on human standards. In any event, it’s crucial to keep in mind that your dog’s life can be prolonged and its quality of life enhanced with a healthy lifestyle, appropriate diet, and frequent trips to the vet.
Lebo"s Theory
A. Lebo, a French veterinarian, proposed a more precise method. In addition to life expectancy indicators, the physical and psycho-emotional development traits of pets were considered when estimating the age of dogs. The theory’s fallacy was that dogs, according to Lebo, aged four "human" years every year beginning at two years of age, but this is untrue. This kind of math is typical only for small breed representatives:
| Dogs | Human |
|---|---|
| 1 year | 15 years |
| 2 years | 24 years |
| 3 years | 28 years |
| 4 years | 32 years |
| … | +4 years |
| 16 years | 80 years |
The physiology of several hundred dogs was studied by the French veterinarian, who used this information to draw his conclusions. But it ignored their unique traits and conditions of confinement, which have a substantial impact on the mental and physical capacities of pets in addition to determining how long they will live.
Kleiber"s Law
The Swiss biochemist Max Kleiber came closest to the truth with his theory, which was based on the animal law of metabolism. He conducted numerous experiments before concluding that larger animals live longer.
This is true generally, but it operates differently with dogs. In contravention of Kleiber’s metabolic law, St. Bernards and Labradors live 10–12 years, whereas Pekingese live 14–16 years. They are also different in terms of their "human" age at the same moment, and the biological age difference increases with age:
| Dog"s age | 1 year | 2 years | 5 years | 7 years | 10 years | 12 years | 16 years |
|---|---|---|---|---|---|---|---|
| Pekingese | 15 years | 23 years | 36 years | 44 years | 60 years | 68 years | 84 years |
| Husky | 13 years | 29 years | 42 years | 51 year | 65 years | 74 years | 87 years |
| Labrador | 14 years | 29 years | 45 years | 55 years | 72 years | 82 years | 99 years |
But keep in mind that there are always exceptions to the rule. Scientific research has demonstrated that the bodies of small breed dogs contain compounds that slow down the aging process. It appears that they have lived a long life because of the natural world. However, a pet’s chances of outliving a "heavyweight" peer are diminished if it lives in unfavorable circumstances.
Consequently, the conclusion is that comparing the life expectancy of dogs and humans is only possible under certain conditions. Numerous elements, including nutrition, environment, and heredity, can either shorten or lengthen the time our four-legged friend stays with us.
Table of dog age in human years
We have presented the age of a dog in relation to human age. The table shows that, for example, at 2 years old, small breed pets are 23 years old in human years, and larger animals are physically developed as well as 28-29 year old people. By the age of 5, the difference in development between dogs of different breeds is more noticeable and is 3-4 years. At 10 years old, when all dogs have already entered the aging phase, small pets are still quite vigorous, medium-sized animals feel like people of retirement age, representatives of large breeds – like 72-year-old old men, and giants, by human standards, age up to 86 years.
| Dog age | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| small breed dogs | 15 | 23 | 28 | 32 | 36 | 40 | 44 | 48 | 52 | 56 | 60 | 64 | 68 | 72 | 76 |
| medium breed dogs | 15 | 29 | 34 | 38 | 42 | 47 | 51 | 56 | 60 | 65 | 69 | 74 | 78 | 78 | 83 |
| large breed dogs breeds | 14 | 28 | 35 | 40 | 45 | 50 | 55 | 61 | 66 | 72 | 72 | 82 | 88 | 88 | 93 |
| giants | 12 | 28 | 35 | 45 | 49 | 56 | 64 | 71 | 78 | 86 | 93 | 101 | 108 | 108 | 115 |
You must take into account additional factors that impact the growth and development of the dog when determining its age in human years. The breed’s traits, the parents’ genetic health, and the conditions of incarceration can all affect the ratios, even within a single group.
| Dog"s Age (Years) | Human Equivalent (Years) |
| 1 | 15 |
| 2 | 24 |
| 3 | 28 |
| 4 | 32 |
| 5 | 36 |
| 6 | 40 |
| 7 | 44 |
| 8 | 48 |
| 9 | 52 |
| 10 | 56 |
| 11 | 60 |
| 12 | 64 |
| 13 | 68 |
| 14 | 72 |
| 15 | 76 |
Gaining an understanding of your dog’s age in human terms can help you better understand their life stage and potential needs. A dog’s age has an impact on their energy levels, health, and behavior, just like it does on humans.
Although it’s widely accepted, the "seven dog years to one human year" ratio is oversimplified. Your dog’s rate of aging can be significantly influenced by factors such as breed, size, and health. Larger breeds age more quickly than smaller breeds, which typically live longer and mature more slowly.
You can help your dog live a long and happy life by anticipating their needs, which range from exercise and nutrition to veterinary care and company, by understanding how your dog’s age corresponds with human years.
There’s more to figuring out a dog’s age in human terms than just multiplying its age by a constant, say seven. The size, breed, and general health of a dog all affect how old they get. Larger breeds age more quickly than smaller breeds, which typically live longer and mature more slowly. By being aware of these variations, you can more precisely determine the human equivalent age of your dog and gain more insight into their life stage and maintenance requirements.
