Since you don't speak the same language as your dog, your body language plays an important role in both preparing him for training and during training.
Dogs are masters at nonverbal communication.
They can communicate a variety of needs and desires to you through their behavior. For example, at dinner time you will likely find your dog spread out near the table with his chin flat on the floor and his eyes following the meat platter as it is passed around the table. He is actually begging. Without even knowing it, you may be communicating important messages to your dog through your body language. And, threatening and overpowering body language may discourage him from responding to obedience training and encourage behavior problems such as wetting, chewing, barking or biting out of fear.
