Many dogs usually look cute and obedient, giving the impression that they live in peace and are not aggressive. However, when they are under mental stress or fear, they will still bite. If the parents think that the dog's biting is showing off to the parents and condone it, the dog will think that he is the stronger one when he grows up. If the dog is not strictly disciplined at this time, it will develop a bad habit of biting.

When a dog bites someone, the first step is to reprimand it promptly and severely. Even small breeds have sharp teeth and are very dangerous to parents. Their bad habit of biting must be eliminated as soon as possible. After your dog bites, you can scold it by holding its chin, or roll a magazine into a tube and knock it on the floor to make a noise to scare it. These are all very effective methods. After the parent reprimands the dog, it will calm down when it is frightened. At this time, it should be praised.

If your dog likes to bite strangers, you can eliminate the dog’s fear of outsiders with the help of friends. You can ask a friend to feed the dog food, and let the dog see the food being handed to the friend from the parent, so that the dog understands that this person is trusted by the parent and is not a dangerous person. After the dog eats food fed by a friend, two people should praise it together, so that it can gradually get used to contact with strangers.
