Animal Instincts Double Training Clicker

Description

Animal Instincts Double Training Clicker has two buttons, each of which when pressed make a different sound. You can use the Double Training Clicker to train one pet, with one sound as a cue for a specific command such as Come and the other as a marker which means a reward is coming. The Double Training Clicker can also be used to train two pets at the same time.
Like traditional training techniques simply assert your authority while clicking this then your dog will eventually respond to just the click when misbehaving.

You could train your dog to come back with just the click, no shouting needed.
