The Carrot Stick is a fundamental product in the Parelli Program. It acts as an extension of your arm when in the saddle and on the ground giving you a more extended reach for a closer communication. It is not a whip. You can stroke, guide and support your horse while teaching him the Parelli fundamentals. It is especially valuable on your journey to bridle-less riding.
You can find the Savvy String most often at the end of a Carrot Stick helping you get your horses respect during groundwork.
