The Mustang is the embodiment of the spirit and freedom of the early development of the United States. It is often thought of as a symbol of the American West and is considered one of the native American horses. Free roaming Mustangs are primarily wild horses, but they are quite often captured and gentled. The American Mustang is favoured for its rugged toughness and endurance. They have an independent spirit and will do as they please, but they are highly intelligent. With good treatment and proper training they are quick to learn.
