The first is to train the puppy's reaction ability. The dog owner can pretend to be a stranger himself, and then do something harmful to the puppy after entering the house, so that the puppy can feel that he is in danger and improve the puppy's reaction ability. However, when teasing the puppy, it is necessary to change the way, let the puppy experience different teasing methods, and then be able to cope with all kinds of injuries. At the same time, when hiding yourself, don't stick to the same place too much, which will hinder the development of the puppy's reaction ability.
Secondly, we should train the puppy's biting ability, that is to say, after stimulating the puppy, the dog owner should put on some protective measures to make the puppy bite as much as possible, but there can also be some resistance, which can stimulate the puppy's desire to win, and then train a very strong puppy, but only if he protects himself and can't let the puppy bite himself. The dog owner should always pretend to be different strangers, so that the puppy can distinguish more bad guys and keep letting the puppy.
Finally, it is necessary to cultivate the puppy's awareness of self-protection and protection of its owner. That is to say, the owner must act scared when facing dangerous things, and then run quickly to let the puppy see that he is threatened, so that the puppy can have the consciousness of protecting his owner. But also let the puppy realize that he is threatened and can attack the puppy when teasing it, thus stimulating the puppy's aggressive behavior. But the most important thing is that the dog owner must have enough care for the puppy, and must spend more time with the puppy in daily life to promote the feelings between himself and the puppy.
