2 hour DVD If you've been experimenting with clicker training and you've reached the stage where your horse is "mugging" you with behavior, you need this video. As your horse catches on to the clicker game, he'll become an enthusiastic player. As soon as he sees you, he'll stars throwing clicker trained behaviors at you. At first this can be amusing, but it can also feel a little out of control. So at this point you need to learn about cues and the concept of stimulus control.
