How many kinds of dogs are there in the world? what was the name?

How many kinds of dogs are there in the world? A large number of recent genetic studies show that there are about 450 kinds of dogs in existence. Scientists have determined through research that the ancestor of dogs is wolves, and humans have kept dogs since about 654.38 million years ago, and selectively used different kinds of dogs for different purposes. For example, a "petite" dog is used to hunt foxes or rabbits, and a tall dog is used to look after cattle.

The custom of keeping dogs is very common in the world now, and it exists in all ethnic groups all over the world. Where there are human beings, there are such loyal animals. In the snowy north, it pulls sleds for people. Among hunting nations, it helps people hunt animals. In more places, it is kept fat and fat as a human pet. ...

According to statistics, there are more than 450 domestic dog breeds in the world. They vary in size, from wolves to cats. Their appearance and coat color are so different and varied that it is almost hard to believe that they are the same animal, but all the differences are the result of people's domestication. Therefore, Linnaeus, a famous Swedish biologist who founded the animal classification system and animal naming method, classified all domestic dogs in the world into one category and named them "domestic dogs", which has been in use ever since.

There are many kinds of dogs, but most scholars believe that dogs evolved from wolves. More than 10 thousand years ago or even earlier, perhaps because of the temptation of food, some wolves gave up wild life and approached the human life circle and stayed. While sharing delicious food, years have washed away the ferocious nature of wolves, and they have become gentle and docile. From then on, people and some special wolves, which we later called dogs, began to hunt together, evolved together, and walked through the long river of time together, from rivals competing for food to friends who trusted each other.

Since the dog became a "silent friend" after participating in human activities, people found that it has a keen sense of smell, loyalty and courage, and has the ability to track, defend, fight and hunt, so it began to be domesticated consciously and purposefully. Take them out hunting, use them to watch the house, train them to be "inspectors" and perform. With the progress of human society and the continuous development, improvement and improvement of production and life practice, there are more and more kinds of dogs and their uses are more and more extensive. After long-term unremitting observation, selection, improvement, domestication and training, domestic dogs with different characteristics, qualities and functions have been domesticated and cultivated.

At present, there are two commonly used and easy-to-understand classification methods. One is to classify dogs according to their uses, such as pet dogs, gun hounds, working dogs and companion dogs. However, because there are too many kinds of dogs, and the morphology and pedigree of modern dogs are very complicated, many kinds of dogs are widely used. It is really very difficult to classify a large number of breeds correctly and reasonably, so it is easier to classify dogs according to their size. According to this classification method, dogs whose body height is less than 25.4 cm (10 inch) belong to subminiature dogs, and most of them belong to pet dogs. Small dogs with a height of 25.5 ~ 40.7 cm (10 ~16 inches) are mostly pet dogs. Medium-sized dogs with a body height of 40.7 ~ 6 cm (16 ~ 24 inches) are mainly used for nursing. Large dogs are those whose height is above 6 1 cm (24 inches). Large dogs are considered as the most attractive type by dog lovers. Usually, small and medium-sized dogs are owned by women, while large dogs are dominated and raised by men. Large dogs can be used as military dogs, police dogs, hunting dogs, protective working dogs, racing dogs, guide dogs, sheepdogs and so on. This is also a major feature of them.
