# What does the age of a dog and a man depend on?

The dog is the first animal that has tamed a person. These four-legged friends accompany people from ancient times, one might say, on the heels. And it is very unfortunate that the life of these devoted pets is much more fleeting than the life of their owners. Consider the factors that determine the age of the dog and the person.

## The story of taming four-footed friends

The friendship between man and dog began in the distant past. Even before the end it is not known who was the first ancestor of a four-footed pet - a wolf or a jackal. Opinions were divided, and it is believed that even then the division of dogs began according to various external features and characteristics of character. The tamed wolf was more suited to hunting, and the more restrained jackal guarded the dwellings. Growing up from a small puppy, the dog became part of the family. And, unfortunately, after many years it became obvious that the life of the pet is much shorter than the human. For example, a teenager who has a four-legged friend from infancy will not even have time to talk to him when he is an adult. A faithful pet will turn out to be a decrepit old man. It is commonly believed that almost always people live 7 times longer than dogs. But this indicator can vary depending on the size of the dog and its weight. Consider the data in the table below.

## Dependence of the life expectancy of a dog on the mass of its body

As the main indicator for comparison, the pet's weight is always used. In this table, the internal cells of the table are the life expectancy of a person. All information is averaged data, which are the result of many years of research.

Table "The ratio of the age of a dog and a person"

 Age of the dog (calendar years) Average Dog weight Up to 10 kg From 11 to 30 kg Over 31 kg 0.5 10 1 15 15 15 13 2 20 23 24 21 3 28 28 29 28 4 33 32 36 35 5 37 35 38 41 6th 41 40 43 47 7th 45 44 47 54 8 50 48 55 61 9 53 52 59 69 10 57 56 63 75 eleven 62 60 70 83 12 67 64 74 90 13 70 68 80 97 14 73 72 83 101 15 77 76 90 110

The above table shows the age of the dog and the man clearly shows their ratio, depending on the weight of the pet. But is this indicator always the main one? Let's figure out what other factors affect the life expectancy of a four-legged friend. And also later in this article, we pay special attention to the importance of the main characteristic of a pet - its breed.

## How is the age of the dog and man determined?

Agree that not always the main reason that affects the life expectancy of a pet is its size. There are many cases when small, for example, lap-dogs did not survive to ten years, and large hunting dogs served faithfully and faithfully longer than fifteen. Below are the main factors that can affect in one way or another on the age of the dog and man:

1. The size. On average, the life expectancy of small dogs can be about 1.5 times higher than that of large dogs.
2. Breed. Dwarves tend to live a little longer.
3. Floor. Just like in humans, the female half is less susceptible to many diseases and more enduring.
4. Sterilization. This factor can prolong the life of the pet for several years.
5. Conditions of detention. No doubt, indoor pets will please you with their communication for a longer time.
6. Individual characteristics. Despite all the above reasons, each dog has its own characteristics, data from birth. After all, even in one litter can be strong and weak puppies.

## How did the different breeds of dogs?

In ancient times tamed animals were universal: they guarded the dwelling, and went hunting. Later, people began to notice differences in habits, characters and abilities of pets. One dog was an excellent watchman and at the same time could not distinguish himself by tracking down a wild beast. The other, on the contrary, was eager for battle and successfully performed duties on hunting due to the impulsiveness of his character. So the division of dogs into the main groups of breeds began: guard, hunting and decorative. Then each of them was gradually sorted into more specific groups depending on the destination. For example, hunting groups were grouped according to the type of activity (northerners, hounds, cops, small animals, large-scale prey, etc.), and decorative ones by external signs. A lot of work in this area went to breeders. After all, purebred dogs must strictly meet certain requirements. In this regard, they are more susceptible to various diseases, and hence the age of the dog and man will not be treated as 1 to 7, but somewhat differently.

## The mongrel is not at all a mongrel animal

Do you think that your dog is "without a clan, without a tribe"? But it turns out that all the mongrels are heirs, possibly even several breeds. Having absorbed in themselves all the best, many of them, as well as the ancient universal dog, can successfully perform the functions of a guard dog and an active hunter if necessary. In addition, these loyal friends are much stronger for the health of effeminate pedigreed brothers. Agree that very few people are particularly worried about the need to inculcate domestic dogs from various diseases. Sometimes this is even beneficial, since they are more resistant to immunity. So, the probability of getting sick is reduced, increasing life expectancy. Therefore, with good care and favorable conditions of keeping, the age of the dog and the person will clearly demonstrate that the mongrels can often be much stronger than thoroughbred pets.
