Nakota Horses - Some say that the breed is descended from the remnants of Sitting Bull's horse herd when he surrendered in 1881. DNA testing has revealed that they aren't as strongly of the Spanish Colonial type but they are still historic. Members of the breed are often blue roan, which is a color rare in other breeds, although black and gray are also common. Other, less common, colors include red roan, bay, chestnut, dun, grullo and palomino. Pinto patterns occur occasionally.
