Happy Mouth English Dee Ring Snaffle Bits
The Dee Ring Snaffle English Equestrian Bit is a compromise between an eggbutt and a full cheek snaffle. It has vertical shanks that extend above and below the mouthpiece, and these are joined on the top and bottom by a D-shaped ring on swivel joints. Like the eggbutt, it helps prevent pinching at the corners of the mouth, though generally without as much bulk as an eggbutt, and it provides fairly substantial lateral control through the vertical shanks, though without the dangers posed by the arms on a full cheek snaffle. Because of this combination of control and safety, the dee ring snaffle has been popular in horse racing and jumping disciplines.
