The Day Hand Three Piece Dog Bone Bit is an excellent choice for stronger, stiffer horses that require more lateral softness and control during the transition from direct reining to neck reining. The locked sweet iron twisted mouthpiece offers a direct pull while remaining palatable and flexible in the horse's mouth. Sweet iron mouthpiece promotes salivation for a supple and comfortable fit. This material is designed to rust naturally and imparts a sweet taste to the horse. Additionally, the copper rings on the dog bone are perfect for horses that tend to be busy and enjoy having something to occupy their mouths during training and while focusing on tasks.
