During this exercise, you are teaching your dog a few things. You are teaching them the communication channels, and you are teaching them that it's a good thing to look at you. First get the dog’s attention, and once the dog is looking at you, you use your continuation marker and then you deliver the reward. Once your dog eats the reward and looks back at you, you are going to use your terminal-marker and move away from your dog, encouraging your dog to come and get the reward. You will continue to do sessions of this exercise until your dog is conditioned to these two markers.
