The training clicker is a small plastic box with a metal tongue that makes a distinctive sound when pressed.
A click becomes a clear signal to the dog for doing something right. The training clicker can be incorporated into any training exercise. Once the dog has responded correctly to any command such as "sit"," heel", "down" or "come" etc., sound the clicker with a treat reward to follow. By repeating this exercise, the dog quickly learns that the click means he has responded correctly.
Most dogs are highly sound sensitive, set the volume by sliding the adjustable control to suit your dog.
