Young bucking horses are initially introduced to work with cloth dummies attached to the saddle. Others are already well-trained on the ground. Some champion bucking horses got their start as spoiled riding horses that learned to quickly and effectively unseat riders. Due to the rigors of travel and the short bursts of high intensity work required, most horses in a bucking string are at least 6 or 7 years old before they are used extensively, and are expected to be sound performers for many years. Awards are given to the owners of the best bucking horses, who are respected as equine athletes and perform for many years. Many are retired to pasture at the end of their careers. Many bucking horses understand their job well and reduce or stop their bucking, even while still wearing a flank strap, as soon as they either unseat the rider or hear the buzzer. Likewise, some bulls appear to understand that their "job" is to throw the rider; they learned not to buck when in the chute and buck far less once the rider is thrown.
