Horse control device

A bridle bit and hackamore are disclosed. Each includes a pair of cheek pieces. Each cheek piece includes a lower rein ring and an upper headstall ring. A nose band and adjustable curb strap are joined at their ends to form a continuous loop. The loop is slidable through lower and upper slide rings on a purchase portion of each cheek piece. By adjusting the length of the curb strap, the loop can be adjusted to fit any horse. When the bit or hackamore are part of a bridle, and the reins are tightened, the loop applies simultaneous, even and predictable pressure to the horse's nose and curb. A lower strap portion for connection to a tie down may be connected at its opposite ends to the loop. The lower strap portion may be slidable through another slide ring on each cheek piece.
