Dressage order is a type of horse riding discipline which requires the horse to perform a series of movements in a specific order. The term 'dressage order' is often used to refer to the TROT, which is a two-beat gait that is performed at a steady speed. The TROT is the most basic of the dressage movements and is usually the first one that riders learn. It is also the foundation for more advanced movements such as the canter and the gallop.
