Abstract: A control leader for horses is adapted to mount onto a horse's head either solely or in conjunction with a standard horse halter. The control leader includes a brow member and a crown member which encircle the horse's ears and which are interconnected at a position immediately beneath the horse's ears on opposite sides of the horse's head, and a flexible leader member which is attached to the brow and the crown members beneath the horse's ear, which leader member hangs freely therefrom so as to have a looped portion in freely hanging, spaced-apart relation to the horse's throat. The crown member is substantially rigid in a direction normal to its longitudinal axis so that it has a substantially non-deformable cross-section. This crown member is preferably formed of wire or chain.
