My parents took their children to play in front of my shop, and I stopped them from teasing my dog many times. They came home to me and said that the child's hand was bitten by a dog. What should I do? According to what you said, you are both responsible. You find that children often tease dogs, so you should tie them up. The parents of the child did not take care of the child, and the parents of the child did not fulfill their responsibilities. You should consult with his family. If your dog is tied up, his family will have nothing to say about it. Your shop is in the street, you'd better tie up the dog, so it's easier for the dog to get into trouble when he grows up.
