This kit contains an iclick. This is a clicker that uses a quiet click which is good for sound sensitive animals, is always in a clickable position, is sized to be hidden in the palm of your hand and is disabled-friendly so it can be clicked with a palm or a chin too.
The kit also has a set of CLICK A TRICK cards. These teach manners and basic behaviours in 10 easy steps. Things covered include "come here", "sit", "down" etc. They will also help you to teach leash manners, speak, find the keys etc.
