Question: are happy mouth bits dressage legal?
Answer: ‚ The Happy Mouth Double Jointed Loose Ring Snaffle is allowed at USEF/ USDF competitions because only the center plastic piece rotates, not the entire linkage. Only a single rotating piece is permitted. ... See Figure A, #6 of the USEF Dressage Rules. It is not allowed as a bridoon in a double bridle.
