Why can't a dog with five claws be kept?
A superstition says that a dog with five claws is unlucky, and it can't be kept alive even if it can't be killed. Other dogs only have four claws, and five-claw dogs have five. Some old people are superstitious and think it will hurt their families. Another way of saying it is that this kind of dog is fierce and not suitable for breeding.
It is only the feudal superstition of the old people to say that a dog with five claws is unlucky. Believers will feel that they can't be killed or raised, while unbelievers will raise them. I don't think it's a big problem to spend tens of dollars on a minor operation in a pet clinic or hospital. Some dogs have wolf toes, slightly higher than normal toes, and some dogs have two wolf toes on one foot. This is an atavism, which is normal.
Extended data:
The reason why dogs have five claws:
A dog with five claws is a dog with wolf toes, which means it is related to some kind of shepherd dog or German shepherd dog.
Five claws are called wolf claws, which is an atavism. Under normal circumstances, a normal dog should have only four claws on its hind legs. The appearance of five claws is an atavism. The ancestor of a dog is a wolf, and the wolf has five claws, which is a rare but existing phenomenon. Wolf's toe refers to the toe other than the normal first five and last four, which is the part that the dog should have degraded and has little significance and can be removed.
Some dogs, like huskies, have natural wolf toes, which are usually removed within 10 days after the puppy is born. This is a very simple surgical operation. The significance of this operation is to avoid the pain caused by accidental injury of the wolf's toe and the overgrowth of the wolf's toe embedded in the limb in the future, but at present, it is more necessary to participate in the dog exhibition to remove the dog's toe.
