The Dog Training Clicker promote effective communication with your dog, and help you shape desired behaviors. The big-button clicker delivers a clear, loud click to create positive reinforcement training for your dog; it also works great for training cats or even horses. Clicker training is a highly effective method of training because it precisely “marks” the behavior you want to teach using a distinct sound she doesn’t otherwise hear throughout the day. The “click” indicates she’s done well and that a reward is coming. These clickers come in a variety of fun colors and the convenient elastic band allows you to wear the clicker on your wrist so you always have it handy while training.
