The “come on leash” exercise is practiced initially from a sit/stay. Once your dog is on a sit/stay, walk to the end of the leash, face your dog, and using his name, give the “come” command. At this time, the dog should come in a controlled manner and sit directly in front of you. If he does not respond when asked to “come”, repeat the come command with a firm snap toward your body. As the dog is moving toward you, slide your hand down the leash toward the dog’s neck. This will put your hand in the proper position to correct the dog if he does not sit when he comes to you. If the dog moves before he is called, you should heel him back to where he was, tell him to “sit”, and give a sharp snap up and forward, while repeating the “stay" command. Never stand directly in front of your dog — go to the right side, left side or behind.
When your dog comes to you, he should sit directly in front of you—not off-center. If his rear end is off to the right, put your left hand on his collar and pull him directly forward, towards your knee. If his rear end is off to the left, put your right hand on his collar and pull him directly forward, towards your knee.
