The horse thumb|A bucking horse at pasture during the off season The bucking horse is usually a mare, but occasionally, a gelding (a castrated male horse) is used. Bucking horses usually travel in close quarters and are housed in a herd setting, geldings are generally less disruptive and more prone to get along with one another. Mares are also used, and while a mixed herd of mares and geldings is a bit more prone to disruptions, they can be kept together without great difficulties. Stallions are less common, because they can be disruptive in a herd and may fight if there are mares present.
