The Colorado Rangerbred was named for its Colorado High Plains origin. Despite appearances, the Rangerbred is not a type of Appaloosa. It has its own unique heritage. However, many Rangerbreds are double-registered with the Appaloosa Horse Clubs of both the United States and Canada. There is a one in ten chance that an Appaloosa is a "Lost" Rangerbred.
The Fjord is one of the world's oldest and purest breeds. It is believed that the ancestors of the modern Fjord horse migrated to Norway and were domesticated over 4,000 years ago. Archaeological excavations at Viking burial sites indicate that the Fjord horse type has been selectively bred for at least 2,000 years.
