Dutch Harness Horse stallion Crescendo HBC. DHH, also known as Tuigpaard is a part of KWPN studbook. Its ancestors are the local Gelderlanders and Groningers but instead of being top-quality riding horses, they're bred to be top-quality harness horses. They have flashy movements and elegant conformation. Black, bay and chestnut are the most common colors, often with sabino markings, but there are also grays, roans, cream dilutes, and some very rare tobianos.
