Surely I have heard on more than one occasion the theory that one year of a human's life is equivalent to seven years of a dog's life. However, this statement is nothing more than a myth. Dog's age at a completely different rate than ours, so to calculate life expectancy, a variety of factors must be taken into account, and breed is one of the most important.
If you are wondering how long a dog lives, we recommend that you join us on the following dog57 article in which we explain everything you need to know about dog life expectancy according to the breed.
Factors that affect a dog's life expectancy
Surely you have heard on some occasions that small dogs have a longer average lifespan than large dogs. However, the breed is not the only factor affecting the longevity of our pets. In this section, we explain the different conditions that can determine a dog's life expectancy.
breed or size
As a rule, larger mammalian species have a longer life span than smaller species. For example, it is known to all that elephants or whales are creatures that live much longer than mice.
However, this fact is in contrast to what occurs within genera of the same species, where there is evidence that within species, the largest individuals have a shorter life expectancy. This is especially evident in dog species, where it was found that for every 2 kg of weight, life expectancy decreases by about one month.
The life expectancy of a species depends on:
The moment he begins his old age.
Your rate of age.
Your birth rate.
In the specific case of dogs, the wide variation in life expectancy between breeds appears to be mainly due to the rate of aging. Large dogs, due to their higher growth rate and greater metabolic wear and tear on their bodies, age at a significantly faster rate than young dogs, and are therefore lesser-lived animals.
If at this point you are wondering about the length of the year in dogs, you should know that there is no single answer. The rate of aging varies with the age and size of the breed, so we must take these factors into account when calculating the equivalence between human and dog life years. Here's how you can calculate this correlation:
To start, we should consider that a dog's first year corresponds to about 15 years in small/medium breeds and about 16 years in large breeds.
At two years of age, dogs have the equivalent of about 24 human years.
From then on, we will add 5 human years for each dog year. That is, 3 years for dogs corresponds to 29 human years, 4 years for dogs corresponds to 34 human years, and 5 years for dogs corresponds to 39 human years.
From the age of 5, we will add for each dog 4 human years in small breeds, 6 human years in medium breeds, and 8 human years in large breeds.
Care
We must know that although a better quality of life does not prevent the aging process, it does delay it. Therefore, improving the quality of all the environmental factors that are in our power will be necessary to make aging a less severe and aggressive stage for our pets.
Below, we list the main precautions that help delay the aging of dogs and, in turn, extend their life expectancy:
Food: A balanced diet according to the requirements of each vital stage will be essential to keeping our pets healthy.
Physical exercise: In the same way, daily physical exercise, according to the needs of each race and age, will help maintain good health, prevent obesity and all associated diseases. How much exercise should a dog do per day?
Hygiene: Understand hygiene not only in terms of the cleanliness of our pet (brushing, bathrooms, etc.) but also as the cleanliness of the environment in which it is located.
Vaccination and deworming schedule: Adhering to vaccination and deworming schedule will prevent a variety of infectious and parasitic diseases, some of which are serious and even fatal. Feel free to refer to the dog vaccination calendar in this post that we recommend.
Veterinary examinations: Regular veterinary examinations will allow any disease process to be detected in its early stages and to start treatment early, which will improve the outlook and life expectancy of the animals.
How long does a small dog live?
Small breed dogs, such as Chihuahuas, poodles, Pomeranians, or Yorkshire Terriers, live from 12 to 17 years. However, there are some particularly long-lived individuals of small breeds that are over 20 years old.
How many years does the average dog live?
The life expectancy of medium-sized dogs, such as the beagle, cocker spaniel, bull terrier, or English bulldog, is 10 to 15 years. That is, they are somewhat younger than small dogs.
How many years does a large dog live?
The life expectancy of large dogs such as German Shepherds, Boxers, Labrador Retrievers, and Golden Retrievers is 8 to 12 years. In the case of giant breeds, such as the Mastiff, Newfoundland, or Great Dane, life expectancy drops to 6-11 years.
Some dog breeds and their life expectancy
Although we have already talked in general about the longevity of dogs depending on their breed, in this section we will more specifically detail the life expectancy of some of the most popular dog breeds:
Beagle: 12-15 years
Maltese Bichon: 12-15 years
Border Collie: 12-13 years
Boston Terrier: 12-15 years
Boxers: 9-12 years
Bull Terrier: 10-14 years
French Bulldog: 10-12 years
English Bulldog: 8-10 years
Poodles: 12-15 years
Chihuahua: 12-20 years
Chow Chow: 9-12 years old
Cocker Spaniel: 12-15 years
Doberman Pincher: 10-13 years
Saluki: 10-14 years
Golden Retriever: 10-15 years
The Great Dane: 6-8 years
Labrador retriever: 10-13 years
Pyrenean Mastiff: 7-14 years
German Shepherd: 9-13 years
Pitbull or American Bulldog: 8-15 years
Pomeranian: 12-16 years
Shih Tzu: 10-16 years old
Dachshund: 14-17 years
West Highland White Terrier: 12-16 years old
Yorkshire: 13-16 years
However, you should remember that this data is only indicative. As we've explained throughout the article, many other factors can affect a dog's life expectancy. Therefore, we recommend taking these values as an approximation only.
