Here is a copy of an article on gaits of gold on the missouri fox trotter. I thought it was interesting.
If you’re looking for a gaited horse with a lot of cow sense, then you might investigate the Missouri Fox Trotting Horse. These animals were originally bred by cattlemen in the Ozarks. These men required horses as rugged as they were, who were smooth gaited, sure-footed and quick enough to round up cattle from the hills and hollers of the mountains. These horses had to outsmart and out maneuver a wily ‘hills’ cow.
The typical Missouri Fox Trotting horse boasts these characteristics. They often have greater muscle bulk than their TWH cousin–appearing more akin to an American Quarter Horse than to an American Saddlebred, for example. The standard fox trot gait has a long, low stride in front and a higher, lifting and shorter length stride behind . Fox Trotters generally have strong loins, broad chests, low set stifles and hocks, and short cannons. They excel at sports requiring quick spurts of energy, tight turns, and quick thinking. Some lines still demonstrate a lot of cow sense.
