In Portugal, the Lusitano is used in every equestrian activity, from dressage and working equitation to hunting, mounted bullfighting, and farm work. Though we participate in every discipline and have won the highest awards in many categories, Haras Dos Cavaleiros aims to specialize in working equitation, the maximum versatility discipline, which is based on the traditional riding of major European countries. It is a contest featuring field elements such as the gate, bridge, zig zag, and an optional cattle handling phase. The horse for this discipline must be agile, fast, and above all have a very good mind because the obstacles are diverse and represent challenges typically found in the field. Several countries such as Italy, Spain, Portugal, Germany, Sweden, England, France, Holland, Mexico, Belgium, and Austria have hosted international competitions in Working Equitation. Through sponsorship, enthusiasm and example, the goal of Haras Dos Cavaleiros is to help introduce and nurture development of this exciting equestrian discipline in the United States.
