Entrepreneur and professional dog trainer Josh Pitts has taken his love for dog training and channeled it into Clicker Plus. Pitts is a firm believer in clicker training but noticed that many dog owners were inclined to leave their clicker at home when taking their pets out. The reason is clickers can be cumbersome when you are also juggling a leash, treats, and other pet accessories. To answer this problem Pitts developed a simple and unobtrusive clicker in the form of a ring worn on your finger.
This may not mean much to you if you have never heard of clicker training.
