"Natural Tolter This term is sometimes used to refer to a horse whose favorite gait is tolt. This horse might be more difficult to get into trot and/or canter (the Icelandic Horse is truly four and five-gaited and a good trot and canter are prized), and may not have high leg action desired in a competition horse, but might be a good choice for a pleasure rider who wants a horse that is very easy to get, and keep, in tolt."
