The role of dogs in human life

Dogs have taken on a variety of roles in human societies, and humans have used them for hunting, herding, loading, guarding, assisting the police and armed forces, accompanying, and assisting people with disabilities, as well as many humans. They faithfully handed over the security of their lives to these animals.

Many people believe that the first breed of this animal came from gray wolves, but the exact time and place of its domestication is not known. A 2014 study found that dog breeds were separated from gray wolves 27,000 to 40,000 years ago, but their domestication did not occur at that time because none of the gray wolf populations today are the direct ancestors of dogs. This means that the breed of dog reaches a population of wolves whose wild breed is now extinct.

The time of domestication of dogs is about 11 to 16 thousand years ago and before the beginning of agriculture and animal husbandry in Europe. As a result, it is consistent with archaeological evidence that dogs were domesticated in collector-hunting communities.

Of course, 33,000-year-old dog-like fossils have been found in Siberia, but it is unclear whether these fossils are the ancestors of modern dogs or represent a failed attempt at domestication or wolves that are structurally similar to dogs. They have today. The geographical location of the ancestors of modern dogs is also unknown.

Characteristics of dog life

The newborn puppy grows shortly after birth and becomes an adult dog. So that between the ages of 3 and 5 you can see an adult dog that is going through the most active period of its life at this age.

The maturity of this animal takes a long time. From the age of 7 or 8, they gradually show a decline and decreased activity. Dogs that have reached this age prefer a comfortable and quiet environment and most of them are sleeping and resting during this period, especially in winter, they rest or sleep for hours in warm environments such as by the radiator.

Adult dogs

Adult female dogs usually mature around 6 months of age. Smaller breeds mature earlier and enter the estrus period. Some breeds even have their first menstrual cycle at 4 months of age. On the other hand, large dog breeds may not experience their first period until they are 2 years old.

On average, this happens twice a year or once every 6 months. Also, each dog is different from the other. Some dogs need between 18 months and 2 years to achieve a regular cycle.

Dog longevity

The average lifespan of this faithful animal is between 18 to 20 years. Of course, the lifespan of this animal depends on various factors such as breed, environmental health in which it lives, diet and other factors, but the average is the same as mentioned.

Breeds such as Spitz and Fox Terrier have a long lifespan of 18 to 20 years, and breeds such as Boxer and German Shepherd have a lifespan of up to 12 or 13 years.
