Through long-term domestication, human beings have turned wolves into dogs and changed their wildness and living habits. So the fundamental difference between the two is that dogs obey people's commands and serve human beings, while wolves can't.
The difference between a wolf and a dog:
Eyes: The wolf's eyes often sparkle with fierce light, and his eyebrows are majestic and very domineering. But the dog's eyes are gentle. It can be seen from the huskies evolved from wolves that huskies' eyes have been domesticated into a gentle species by human beings.
Appearance: The wolf's ears stand approximately parallel and vertically, unlike the dog's ears, which usually droop; The wolf's nose and mouth are longer and sharper than those of dogs, and its mouth is wider, its teeth are bigger, its eyes are tilted upward and its position is higher than the bridge of the nose. The hair on the wolf's back is longer than that of the dog, and the chest is wider than that of the dog. The tail is shorter and thicker than the dog's, and its hair is fluffy. It often hangs between the hind limbs, unlike the dog's tail, which is often rolled up.
Behavior: When the wolf can be independent, he will leave his mother to find food alone and rush out of his own world in the law of the jungle world of biology. Dogs need to rely on humans and will be attentive to humans for food, but wolves will not. Wolves can be independent.
Wolves are social animals. When they grow up, wolves will find a group to accept their hunting. They are smart and know how to catch food. Dogs, on the other hand, are naturally sensitive to prey, but when they catch food, they don't share it with their companions.
The male wolf is very responsible to the female wolf. When the female wolf is pregnant, the male wolf will always protect the female wolf. Dogs can't. Dogs are not responsible for their actions.
