Merrill Bits Medium Gag Chain Dogbone Roller

About the Bit

The Merrill Medium Gag with Chain Dogbone Roller is designed for riders who want a soft feel paired with clear communication. The medium shank gives you more authority and lift than a short shank—ideal for horses that need help staying elevated, collected, or responsive at speed.

The chain mouthpiece is naturally softer due to its multiple breaks, offering flexibility and encouraging bend through the ribcage and neck. Combined with the dogbone center and roller, this mouthpiece helps relax the jaw, soften the face, and promote a more willing, supple response. This bit is especially useful for horses that can get stiff or bracy in the bridle.

Balanced, forgiving, and effective, this bit delivers clearer direction with a soft, flexible feel your horse can trust.
