There are also a few times when rearing is considered acceptable by humans. Rearing may be taught as a trick for circus horses and the like. There are also two movements in classical dressage, the Levade and the Pesade, in which the rider asks the horse to set well back on its hindquarters and raise its front legs off of the ground to varying degrees. However, horses properly trained to do any of these movements are taught to respond to very specific commands and only raise their forequarters when given the command.
