Other forms: clickers
A clicker is a small device used to mark good behaviour. Clicker training, use the clicker, click and treat.
The sound itself means nothing to the animal at first: the trainer pairs the click with food until the click alone says yes. The value of a clicker is speed, since it marks the exact instant the dog did the right thing.
