How to translate the dog’s age to human.

Content

Communicating with his smart pet, the owner of the dog may have a very logical question regarding the level of development of a four -legged friend. How old is the pet, if you measure human years? How to translate the dog’s age to human and how many years are still in reserve to enjoy communication with an aged pet?
It will not work to fit the dog’s age under the corresponding age of a person, because the dog aging process differs from the human one. But there are several systems of transferring dog age into human. From the material of the article, you will learn how to determine the age of the dog by special methods: by simplified, by the table of the age of the dog to the age of the person (calculation is made according to certain coefficients).

How to translate the dog’s age to human, how many dogs have a year of life by human standards: calculation

1st version of calculating the age of the dog by human standards (simplified):

According to this technique, 1 year of the dog’s life is equated to 7 human years.

History reference:

In the middle of the twentieth century, veterinarians equated the dog’s age with the following simple ratio: a person lives on average for 70 years, and the life expectancy of a dog is 10 years old, which means that one dog year was equated to 7 human years.

In this common ratio, some social features remain unaccounted for:

The first 20 years of a person’s life pass in full or partial dependence on parents. During this period, a person learns the norms of morality and behavior in society, undergo training in educational institutions, a new family is not created, and there is no need to talk about the birth of offspring - the dilution function becomes accessible much later.
In the abdomen of the world, everything is arranged differently. For a one-year-old pet, whose age in terms of human standards corresponds to 15 years, a similar lifestyle is a real luxury, because the performance of all working functions is quite accessible to him. The animal learns to get food, to take care of itself, to navigate in the surrounding world. The two -year -old pet has already formed character, physically by this time it is considered completely ripened.

Calculation of the age of the dog by human standards by Lebo's theory:

It so happened that the authors of various theories of calculating the age of pets in accordance with human standards are not scientists, not zoologists, but veterinarians. The last all their working time is carried out next to four -legged pets, without delving into the analysis of data, numbers and results of long -term research.
The French veterinarian A. Lebo is the author of the theory, named his name, which takes into account the rapid pace of development of the level of social intelligence of the young dog in the first year of life. Lebo made the conclusions on the basis of the characteristics of the growth and development of people and dogs. The period of puberty of a person and a pet was compared, a period of maturity, as well as life expectancy.
According to Lebo's theory, the level of development of a one-year-old pet can be equated to the human age, corresponding to 15 years, at two years the development of the pet can be correlated with 24 years of human age. One year of the dog’s life during this period is 9 human years, after the first two years of life, he is “added” for 4 human years to the age of the pet.

What did not take into account Lebo in his theory?

The French veterinarian, given the calculation of age, did not take into account the influence of the size of four -legged wards on the features of their level of development.

Claiberg Law

In accordance with the second theory, the age of a four -legged pet is calculated in accordance with the metabolic law of the “three quarters” of Claiberg. The law also turned out to be insolvent.
The reason is as follows: the speed of the main metabolism is depending on the weight of the body.
The pattern is traced here: the larger the animal, the longer the duration of his life. But with the dogs, the Law of Klaberg does not “work”, and the dependence of the weight on the number of years lived is the opposite: dogs of small breeds under normal conditions live longer.
However, the Claiberg law has some truthful moments: with warm -blooded animals, the pattern of correspondence of growth and metabolic rate is not subject to doubt.
For example, if you compare the life expectancy of a mouse and an elephant. According to this scale, the dog occupies the middle place reserved by law. The age of a four -legged favorite will not always be equally correlated with human, because the influence of not only weight, but also the breed of the pet.

According to the Law of Klaiberg, the larger the animal, the longer the duration of his life.

The age of a 78-year-old person corresponds to:

10 years of age of the dog, if it is a giant breed
12-year age, if a large-breed pet
14 years of age, if a medium-sized pet
15-16 summer age if a petty pet

Based on the above, we can conclude regarding the reverse general dependence of the phenomenon inside the species (for example, mouse, horses, people). If we talk about dogs, then the dependence is expressed most clearly.

That Clyberg did not take into account:

The life expectancy of the animal is also associated with the frequency of heartbeat. This is a common rule for representatives of the kingdom of animals. 1 billion abbreviations is the life life of an animal. Small dog breeds live longer, and their heart rate more often.
According to the Law of Claiberg, the life expectancy of 80 kilogram mastiff should exceed the life expectancy of a 2-kilogram chihuahua by 2.5 times. However, in fact, everything is different: a dog of such a large breed lives 1.5 times less.
This can be explained as follows: the insulin-like IFR-1 growth factor is released into the body throughout life, which can not be said about the growth hormone. In dogs, small breeds have more concentration of IFR-1. As a result, the programmed cell death slows down and the dog’s body is not subjected to age -related diseases, which means the aging slows down.

The modern system of transferring human life into dog:

Modern geontologists in their conclusions are based on the fact that age-related changes in the dog are associated with its size. Therefore, do not equate the eight -year age of the dachshund with the same age of Mastino. Yes, not quite a logical approach, because people are the same in age changes, regardless of growth and constitution. But an objective assessment of dog age is possible subject to the separation of rocks into several weight categories.

Objective assessment of dog age is possible subject to the separation of rocks into several weight categories

The first group includes dogs of small breeds, the weight of which does not exceed 10 kg (Chihuahua, Toy-terrier, dwarf poodle, Shi-Tzu, Japanese Khin)
The second group includes dogs of medium breeds, the weight of which reaches 10-25 kg (setters, bulldogs)
The third group includes dogs of large breeds weighing from 25 to 45 kg (Afghan Borza, Labrador)
The last group includes giant dogs weighing more than 45 kg (mastiff, dog)

The first few years of life (3-4 years), the development of dogs, regardless of the breed and size, passes the same way. During this period, three years of dog life correspond to human years of 28 years

After that, the following stage occurs for a giant dog-aging. The body is aging without reducing the pace. If the dog is medium -sized, then its body ages more slowly, and in very small dogs the pace of aging is as slow as possible.

After the pet is 3 years old, it can be added to his age with each subsequent year 4 years by human standards

What are the aging pace of small breeds? After the pet is 3 years old, it can be added to his age with each subsequent years of 4 years by human standards.

For a medium -sized dog, 4.5 years are added when counting, for a large breed dog - an increase in age of 5 years.

How many years have been living, and should dogs live?

The life expectancy of a dog, as mentioned above, is affected by many factors. Among them are the growth of the pet, and his weight, and the state of health. However, the existing injustice is as follows: the century of our cute homemade quadrued pets, the most devoted and loved ones, and shortcomings compared to the life expectancy of other pets. If we talk about parrots, then some species in good conditions live up to 70 years, tortoises, provided that the maintenance is proper, live both 50 and 200 years.

How to determine the biological age of the dog?

The main stages of development of the dog are the first two years of life. At six months, the development of the puppy can be compared with the age of a five -year -old child. In terms of human standards, the most difficult period of transitional age is the first year of dog life.

At the age of two, the development of the dog by human standards corresponds to the 24th age, and at the 3-year or 5 year old the pet is already considered fully formed. Such an age is considered a period of dog maturity, and at the 9th year the pet is already considered old. The 15-year-old dog is a real long-liver.
