The Colorado Ranger Horse breed was officially named in 1934 and Mike Ruby was the President of the Colorado Ranger Horse Association until his death in 1942. The name Colorado Ranger Horse, or Rangerbred, refers to the fact that the horses were bred on the open range in Colorado.
While many Colorado Ranger Horses exhibit the same characteristics as the Appaloosa, (spotted coat, mottled skin, white sclera) the Colorado Ranger Horse Association is not a color registry and registered horse may be solid colored, as well as spotted.
Colorado Ranger Horses are refined horses, due to their Arabian/Barb ancestry and are compact animals, with powerful hindquarters. The average height is 15.2 hh.
