It is important to teach your dog to guard you and the other members of your family against danger. Here are some tips on how to train your dog to protect you.
Use proper commands.
A dog acts according to how it has been trained. The only way to do this is through commands and your own body actions and sounds.     71    Soon, whenever you use the command “Attack!”, your dog will understand that it needs to fight the thing you are pointing at. While you are training the dog to attack, you must also train it to stop the attack.
Encourage socializing（交际）.
It is very important to introduce your puppy to other people and let it interact（互动）with them.
    72    This exercise is very important because it will help the dog distinguish（辨别）between good people and bad people. People who are good will be those who are allowed to come close to it and pat it.
    73   
Teach your dog to keep a check on the house by taking it around the house and making it sniff（嗅）the area. You will need to do this a couple of times so that the dog understands that it needs to keep a check every night. After a few days, the dog will begin to do this exercise on its own. It will check the house and return back indoors.

Giving rewards such as a pat, a hug, verbal praise “Good dog!” or treats is an excellent way of letting the dog know that you are happy with its behavior. Since you are the master, it is your duty to make sure your dog is rewarded for its good behavior and punished for its bad behavior. Punishment involves scolding the dog by using the command “Bad dog!” or “No, very bad!”     75
