Easy-to-use Clickers are used and endorsed by PetSmart's own training professionals. Made exclusively for PetSmart. Have you heard of Clicker Training? It involves the use of a noise-making device or "clicker" to signal to the dog that he has performed an exercise or behavior correctly. When the dog hears the "click," he knows it means he's done something right, and the sound will be followed by a small reward. To learn more about clicker training and other reward-based training techniques, talk with a Smart Pets Training Instructor at the PetSmart store nearest you.
