The term "Dressage Horse" describes horses specifically bred, selected, and trained for dressage competition rather than designating a distinct breed. Dressage, derived from the French word meaning "training," represents systematic gymnastic training developing horses' natural abilities, strength, flexibility, and willingness to perform precise movements from basic walk-trot-canter work through advanced movements including piaffe, passage, pirouettes, and flying changes. While any horse can receive dressage training benefiting basic riding, the term "Dressage Horse" typically refers to horses with specific qualities making them competitive at higher levels of the discipline.
Most competitive dressage horses come from European warmblood breeds specifically developed for sport horse disciplines, including Hanoverians, Dutch Warmbloods, Westphalians, Oldenburgs, Danish Warmbloods, and KWPN (Royal Dutch Sport Horse), among others. These breeds emphasize characteristics essential for dressage success including natural movement quality showing suspension and elasticity, trainable temperaments, appropriate conformation supporting collection and extension, and mental attributes allowing sustained concentration and precision work. Additional breeds competing successfully in dressage include Lusitanos, Andalusians (PRE), Friesians, and occasionally Thoroughbreds, Quarter Horses, or other breeds, though warmbloods dominate upper-level competition.
No single registry governs dressage horses, as multiple warmblood registries and breed organizations maintain studbooks for their respective breeds. However, competitive dressage is governed internationally by the FΓ©dΓ©ration Γquestre Internationale (FEI), which establishes rules and standards for dressage competition from lower levels through Grand Prix and championship events including World Equestrian Games and Olympics. National organizations such as United States Dressage Federation (USDF), British Dressage, and similar bodies in other countries promote the discipline, organize competitions, and provide educational resources supporting dressage training and competition. Understanding that dressage horses represent a functional type rather than breed helps clarify that success depends on individual horses' qualities and training rather than breed alone, though certain breeding programs have proven particularly successful producing horses with desired attributes.
