Let's look at how a person (master) should behave to qualify to be the leader of the pack.

• Do not let him on the bed.
• Give food only after you have eaten yourself.
• After a long pause, give the command "eat" and thereby allow the dog to eat.
• Do not move your hand away when the dog is aggressive, but keep it close to you. The dog will understand that you are afraid of him if you move your hand away, and it is wrong.
• Never flick the dog's nose with your hand.
• Don't let the dog be the first one out of the house.
