Breeding goals calls for dressage and showjumping horses to be suitable for Grand Prix level riding, while hunter and harness horses should be able to perform at the highest level in their sport. Strict selection procedures ensure that bad-tempered stallions and mares do not go on to produce unmanageable horses, however, the Dutch Warmblood is significantly more sensitive than its Gelderlander and Groningen ancestors. Performance test results allow breeders and buyers to identify horses with amateur-suitable temperaments. All Dutch Warmbloods are selected to be uncomplicated to handle and ride. Among the dressage horses, cooperativeness is paramount as an element of the submission required in that sport. From the show jumpers, a level of courage and reflexivity is required to effectively navigate a course. Since the turn of the millennium, Dutch Warmblood breeding has shifted from breeding a "riding horse" to further specialization into dressage type and jumper type horses. The reason behind the choice for specialisation is the negative genetic correlation between the ability for dressage and show jumping. By dividing the whole population in two subpopulations, faster genetic progress can be achieved in both traits compared to simultaneous selection in the whole population. To protect against losing canter quality in the dressage horse and conformation, gaits and rideability in the jumper type, genetic material continues to be freely exchanged between the two types. The Dutch Warmblood is long-legged but substantial with a smooth topline and dry, expressive head. They are built level to uphill in a rectangular frame. A number of traits are desirable in both directions, such as "long lines" or a rectangular frame, "balanced proportions" and attractiveness. The requirements for the two types differ in the desired interior qualities, but also in form. The exact outline of the Dutch Warmblood varies depending on the pedigree. Medical issues Dutch Warmbloods are sound and long-lived due to the stringent requirements placed on stallions and elite mares. While mild navicular changes, sesamoids, pastern arthritis and bone spavin may be permitted on radiographs, osteochondrosis in the hock or stifle is not allowed. Horses are disqualified from breeding for congenital eye defects, over- or underbite, or a lack of symmetry in stifles, hocks, hooves, or movement. Uses No registry produced more successful international show jumping horses than the KWPN. In 2010, Dutch Warmbloods were ranked #1 in jumping by the World Breeding Federation for Sport Horses (WBFSH). as
