Thoroughbreds are the most popular racing horse in North America. This breed is considered "hot-blooded," which means it's known for agility, speed, and spirit. This is a fine multipurpose horse that often has a career in other equestrian competitions besides racing, such as dressage and jumping. Or they simply live as a companion animal kept for pleasure riding. Because of their fast metabolism, you might need to feed a thoroughbred more food than other breeds, but a standard equine diet should be sufficient. Also, gentle grooming is best for these horses because their skin tends to be more sensitive.
