A double bridle is a bridle that has both a curb
and snaffle bit
, called a bridoon, attached to it. The rider carries two sets of reins, one attached to the curb bit and the other attached to the snaffle bit. The purpose of a double bridle is provide very precise cues to the horse. Very basically, the snaffle is used for horizontal control such as turns, flexion to the sides and controlling speed. The curb is used to control the flexing of the neck and lifting the back, important for doing collected gaits and other precise maneuvers.
Double bridles are most often seen on dressage horses, horses on drill teams and military parade horses. Riders must have very soft, skilled rein aids and know how to make the horse flex correctly. Incorrect use can result in a horse with improper neck flexion, a hollow back and other problems.
Also Known As: full bridle, bit and bridoon, bit and bradoon
