my BF has a 25+ year old TB gelding. This horse dose it tall, he can do low level dressage, any western and cow event and apparently he gaits. He starts to do what looks like a running walk. BF was messing around and found out if he sits likes hes riding a gaited horse he starts to gait (or he will do it heading home and is not aloud to trot). Is it possible to teach them to gait like that or would he have to have a gaited breed in the woodpile? (BF swears hes is a TB and he looks like it, but there is no tattoo or papers to prove it).
