The modern Don is still tough and strong with an independent character. It is bred in large numbers in the Steppes, where it can run free and needs little care from humans. These days the Don is mainly used for endurance riding, for which it is admirably suited. It is used to infuse stamina and hardiness into other breeds. Don Horses are usually brown, or chestnut but bay, black, and gray sometimes occur. Don Horses stand about 15 hands high.
