A crop, sometimes called a riding crop or hunting crop, is a short type of whip without a lash, used in horse riding, part of the family of tools known as horse whips. A dressage whip is made so that the rider can tap the horse behind their leg without having to take their hands off of the horse's reins. ... This type of whip is also often used by sidesaddle riders where it is carried on the right side.
