Dogs also have their own ideas about right and wrong and know who is closer to them. A pet dog's IQ is not low, and he can understand who is good for him and who is not good for him, so when the owner is in danger, he will protect him at the first time.

Nowadays, every family keeps some pet dogs, and dogs are also the most successful example of human domestication of natural creatures. Because the ancestors of dogs are wolves, but they can follow human beings for a long time and eventually become the most loyal partners of human beings. It can not only play the role of guarding the home, but also bring entertainment to our lives. It can be said that pet dogs are the most loyal friends of human beings, and they are also trustworthy. The boy in southern Guizhou was chased and pecked by ducks, and the dog rushed out of protection.

Especially for rural residents, almost every household will keep some dogs, which are used to watch the door or as companions. In our memory, everyone must have a figure of rhubarb in their hearts. The former boy was chased by a flock of ducks, which was very common in the countryside. However, the dogs kept at home don't think so. They think that the little boy is in danger, so they rush out and drive all the ducks away. Because dogs have a certain IQ.

First of all, the reason why pet dogs can protect human beings is that they have a certain IQ. Because humans often place their lives on dogs, it is said that the two sides have developed a relationship of cooperation. Dogs protect their owners, who are based on certain foods. For a long time, this relationship has been engraved in the genes of dogs, so it is my main duty and my bounden duty to understand that protecting human beings. Pet dogs are completely domesticated by humans.

Secondly, it is also because the wild wolf, the ancestor of dogs, has been completely domesticated by human beings. Wolves can't change their nature, but some old, weak and sick people can't, and they can only rely on human beings to survive. Therefore, in the long run, some wolves have a close relationship with human beings and will not do harm to human beings. Once there is any external thing that threatens the safety of human life, then the dog will inevitably respond at the first time.
