3" Cheeks, 5" Mouth. This Western Dee is a great choice when you want a more direct signal than you get with a loose ring snaffle. The Dee ring applies pressure to the horse's cheek on the opposite side of the face from the rein you pull, allowing for better flexion. Reinsman's Sweet & Sour mouthpiece tastes like a green apple dipped in molasses and is sure to become your horse's favorite! The sweet and sour combination causes increased salivation, leading to a more relaxed jaw and a supple mouth. Copper is a soft metal, check for signs of wear before each use.
