3-DVD Set by Moe Strenfel ©2009 To achieve your goals in agility, you need a solid working relationship with your dog and a clear and consistent communication system—often referred to as a “handling system”. A handling system is no more than a set of verbal and physical cues that tell your dog what you want him to do. The foundation of this communication system must be taught on the ground before you teach any piece of agility equipment. Disc 1 covers basic skills, Disc 2 covers handling skills, and Disc 3 covers physical skills. 188 minutes.
