Dogs belong to the spine, vertebrates, lactal gates, mammals, real beast subclase, carnivorous eyes, cracks, and dogs. Chinese is also known as “dogs”, and dogs are distributed around the world. Dogs and horses, cattle, sheep, pigs, and chickens are called “six beasts”. Coster believes that dogs are domesticated from early humans from the ash wolf, and the domestication time is 40,000 years ago to 15,000 years ago. Known as “the most loyal friend of human beings”, it is the pet with the highest breeding rate. Its life span is more than ten years. In Chinese culture, dogs are one of the zodiac signs and 11th among the zodiac signs. Extension information: . The start source of the species The dog is domesticated from the wolf. As early as the era of hunting collection, people have already domesticated dogs as assistants when hunting. Therefore, dogs are the earliest domesticated livestock. Hebei Wu’an Mountain, Henan Xinzheng Pei Gang, Zhejiang Yuyao Hemu and other sites have found dog bones, which proves that its domestication history is long. The dog -shaped dogs unearthed from Sanli River in Jiao County, Shandong, are vivid and realistic, so that we have to see the morphological characteristics of the new Stone Age family dog. The dog bones unearthed from the Banpo site of Xi’an, Shaanxi have small skulls, protruding from the forehead, small kettle teeth, and bent at the edge of the jaw bone. It is very different from the North China wolf, which shows that the history of human domesticated dogs is indeed very early. . behavior Dogs also have “hierarchical systems” when they live in groups. Establishing such an order can maintain the stability of the entire group and reduce the fighting and war caused by the struggle of food, living space and the opposite sex. Before the dog is lying down, it always turns around, and after confirming that there is no danger, you will sleep with peace of mind. The dog’s belly and back like to be caressed by others. This should not touch the top of the head, because it will make it feel depressed and dizziness. Contraindications: Don’t stroke the buttocks and tails of strange dogs. The guidelines of dogs’ behavior to strangers are to judge the strength of the opponent based on the height of their sight. As soon as the stranger approaches, the sense of oppression from above will make it disturbed. If you use a low posture, it will accept it. Reference information Source: Baidu Encyclopedia -Dog

In Chinese culture, dogs are one of the zodiac signs and 11th among the zodiac signs. Pucting information: Animal classified scholars are classified according to the characteristics of the animals (morphology, cells, genetic, physiological, ecological and geographical distribution, etc.), and the animals are divided into 6 main grades in turn, that is, that is, that is, Door, outline, meant, subject, belong to, and species.
The characteristics of animal classification
The characteristics of the basis are still: cell differentiation, formation of embryo, body cavity, symmetrical form, segmentation, bone nature of bones, the nature of bones The characteristics of attached limbs, as well as the occurrence and development of other organs systems, and refer to the division of stratigraphy in geology. The characteristics of dogs
1. The smell sensitivity of dogs is the first of each animal. Blind dogs can use the nose to live like normal dogs. The dog sensitivity of the dog is mainly manifested: one is the degree of sensitivity to the smell; the other is the ability to distinguish the smell. 2. The hearing stress can reach 120,000 Hz, which is 16 times that of humans. It can hear the longest 400 times that of people. Dogs’ discerning ability of the sound direction is also twice the humans, and can distinguish 32 directions.
