The obedience phase includes a series of heeling exercises, some of which are closely in and around a group of people. During the heeling, there is a gun shot test to assure that the dog does not openly react to such sharp noises. There is also a series of field exercises in which the dog is commanded to sit, lie down, and stand while the handler continues to move. From these various positions, the dog is recalled to the handler. With dumbbells of various weights, the dog is required to retrieve on a flat surface, over a one-meter hurdle, and over a six-foot slanted wall. The dog is also asked to run in a straight direction from its handler on command and lie down on a second command. Finally, each dog is expected to stay in a lying down position away from its handler, despite distractions, at the other end of the obedience field, while another dog completes the above exercises. All of the obedience exercises are tests of the dog’s temperament, structural efficiencies, and, very importantly, its willingness to serve its owner.
