Very few Saddlebreds are naturally gaited. They have the natural ability to learn the slow gait and rack, but most are not trained to do them. If they will not be competitive as a five gaited horse, or would be better suited for something else, a trainer will not waste the time training the other gaits. Ask the former owner if he was gaited. If she says no or says that he is three gaited, that means he knows walk, trot, and canter. Explaining how to train the gaits would take too long atm, but I will try to fibd you an article soon.
