2. Severely reprimand. When the dog bites again, you can pinch its mouth with your hands, yell at it not to bite, and pinch its mouth appropriately with your hands.
3. Buy toys. You can buy toys for your dog to distract your dog and let him focus more on the toys.
The last method is very simple. If your dog is particularly skinny, it needs to be beaten. You can put your hands in front of the dog. If the dog bites, just pinch the dog's neck (don't use force, just restrict the dog's mouth from biting you) and hit the dog's mouth with your hands. Tell it not to bite.
You can repeat this training several times a day, and you can change your dog’s biting habit in two to three days. When the dog does not bite people, reward the dog to let it understand the correctness of doing so.
In another three to six months, the dog is in the teething period. At this time, you must buy some teething toys for the dog. Don't give your old slippers or other items to your dog, as this will encourage your dog to develop the habit of tearing down your home.
