How do I train my horse for the dressage phase of working equitation?

The dressage phase in working equitation is evaluated similarly to traditional dressage — horse and rider perform a prescribed test in an arena, and judges score each movement on correctness, rhythm, impulsion, and the overall quality of the partnership. The movements required vary by level but follow the progressive structure of dressage training: walk, trot, and canter work at entry levels, with lateral movements, collection exercises, and more advanced patterns appearing at higher levels. The training approach for the dressage phase is classical dressage development applied with the working horse philosophy in mind. The horse should move forward with genuine impulsion and rhythm, respond to the aids with lightness and without resistance, and carry itself with the self-carriage that correct dressage development produces over time. The specific frame and degree of collection required increases with the level, and training the horse progressively through each level before attempting the next applies here as in traditional dressage. Transitions are as central to working equitation dressage preparation as they are to any dressage training program. The horse that transitions smoothly and promptly between gaits, that can lengthen and shorten within a gait in response to subtle aids, and that maintains its rhythm and frame through every movement demonstrates the quality of training that working equitation dressage judges reward. The difference between working equitation dressage and pure dressage competition is primarily one of emphasis rather than standard. Working equitation dressage rewards correctness and harmony, but it is evaluated in the context of a horse that will also work obstacles and cattle in subsequent phases — a horse that is extremely collected and refined for pure dressage but loses its forward energy and practical confidence under those demands is not an ideal working equitation horse, even if its dressage score is high.
