The National Show Horse, (NSH), originated as a cross between an American Saddlebred and an Arabian horse. It is now established as a separate breed, since the founding of a breed registry in August 1981. Registered animals today may be the offspring of registered NSH parents or may be a combination between an American Saddlebred, Arabian, and a National Show Horse. Non-NSH mares and stallions must be registered with their appropriate registries, and stallions who are Arabian or Saddlebred must additionally be nominated and approved by the NSHR board of directors.
