It is not good to bite anyone. Don't always tie it with a rope when you take it out. You should let it follow you since you were a child. If it is not good, you can train at home. You stay away from it, then call its name and let it come. When it comes, you can give it something to eat, but not too much, a little, to make it interested in the food in your hand. If this happens frequently, you can take it out. If there are few people, don't bring a rope to it. Then call it and it will listen to you. If you give it something to eat, it will listen to you slowly.
Then, the puppy likes to bite. You can buy them some toys, just a tennis ball, and then give them a pair of slippers that they don't want at home. Tell them they can only bite these. If it bites something else, you can hit it, and then ask your family to give it its toys and tell it that it can only play with these, otherwise xx will be angry and hit you! ! The owner who hit it certainly didn't coax it just for a second, so you have no prestige in its heart. You have to play the bad COP and the bad COP, of course, based on what it did wrong.
Usually talk to him more and play with him more. When he was eating, he had to move his dog basin. He is five months old now. If you didn't touch his basin when he was a child, you should try to touch him now, but be careful. Look at your description. Your dog has a bad temper. If you don't move all the time, it will be bad for you if you accidentally move one day! !
Dogs must fight, don't feel bad! ! A word for you, good dogs are made! ! !
