The Starmark™ Clicker Training System is based on the scientific principles of Classical and Operant Conditioning, two proven and well-respected methods of modifying your dog’s behavior and enhancing his training experience. Teach him to repeat behaviors that lead to rewards. The ergonomic Clicker fits comfortably in your hand and features an easy-to-press raised button and a stainless steel rust-resistant clicker element. To reward your dog, click the button and give your pet a treat, so he will learn to associate that action with a reward. Use the included step-by-step training guide for complete details. The guide is approved by the Training Directors of Triple Crown Academy. Clicker attaches easily to a key chain or lanyard, so you can always have it close by.
