Last updated: 10-30-2023

🐾 Welcome to the world of care and love for our four-legged friends! Ever wondered how quickly time flies in a dog's world? With our calculator, you'll find out how many years your furry companion would celebrate in human terms. This is an incredibly useful tool that helps better understand the needs and peculiarities of your four-legged friend. 🎉

How to Determine a Dog's Age in Human Years?

To determine a dog's age in human years, it's important to consider its breed and size. Typically, in the first year of a dog's life, each month is equivalent to about two human years. After that, the differences start to decrease.
It's important to note that large dogs age faster, so the number of years equivalent to human years can vary depending on the breed. 🐕

Methods and Formulas for Calculating a Dog's Age

The Folk Formula for Calculation

There is a belief that each year of a dog's life is equivalent to 7 years of a human's life. However, this formula does not take into account the individual characteristics of each breed. For example, for a dog of a large breed, each year may be equivalent to less than 7 years of a human's life.

Let's consider this with examples of different breeds:

French Bulldog - This breed tends to live a long life. Therefore, 5 years in a French Bulldog can be similar to 35 years in a human.

Siberian Husky - This energetic breed ages quickly. Thus, 5 years in a Husky can be equivalent to 40 years in a human.

Dachshund - Despite its small size, this breed can lead a long and active life. Therefore, 7 years in a Dachshund can be close to 45 years in a human.

Thus, it is important to consider the specific breed and its characteristics when determining the age of your pet. Strive to be attentive to its needs and provide the best care regardless of its age! 🐾❤️

Scientific Research on Dog Aging: What Science Tells Us

In 2019, scientists from the University of California San Diego revealed the secrets of dog aging. It turned out that each dog year is not equivalent to 7 human years. This dependency turned out to be nonlinear and led to the emergence of a new method.

According to the formula: age = 16 * ln(dog's age) + 31 years, we can now accurately determine how many years your fluffy friend really has. 🐾

Our calculator took into account the results of this unique study and adjusted the coefficients based on data from pet insurance companies and veterinary clinics. Now we can provide the most accurate calculations of your pet's age! 🔍 

How do Insurance Companies and Veterinarians Determine a Dog's Age

As a rule, the methodology of the American Veterinary Medical Association is used as a basis. Interestingly, the size of the dog plays an important role. Studies have shown that every 2 kg of weight affect the duration of its life - approximately a month. Although the exact reason for this is still unknown, statistics clearly confirm the correlation between weight and age. 🐾🔍

How Does Age Affect a Dog's Physical Activity?

With age, a dog's physical activity may decrease. Young dogs have more energy and require more activity. Adult dogs can maintain a stable level of activity, but older dogs may require a gentler regimen.
Older dogs may show less resistance to prolonged activity, so it's important to monitor their comfort during walks. 🚶‍♂️


For a dog that is 3 years old:

Small breed: this is about 33 human years. 🐾
Medium breed: this is close to 40 years in humans. 🐶
Large breed: this is similar to 47 years in humans. 🐕

For a dog that is 5 years old:

Small dog (for example, a French Bulldog) - If it is 5 years old, it may correspond to approximately 35 human years. 🐾

Medium-sized dog (for example, a Labrador Retriever) - This dog is also 5 years old, but it may be close to 40 human years. 🐾

Large dog (for example, a German Shepherd) - If it is 5 years old, it may correspond to approximately 45 human years. 🐾
