CLICKERS

A clicker is a small plastic box with a thin sheet of metal inside it that makes a "click" sound when the yellow button is pressed. This "click" sound is used to mark the exact moment that the dog is doing the exercise correctly (it also marks the END of the exercise).  The dog is conditioned to anticipate a reward when it hears a single "click" (never click more than once) and so tries to repeat the behaviour in order to gain another reward.
