The ideal age to start training dromedaries for riding is three years, although they may be stubborn and unruly. At first the camel's head is controlled, and it is later trained to respond to sitting and standing commands, and to allow mounting. At this stage a camel will often try to escape when a trainer tries to mount it. The next stage involves training it to respond to reins. The animal must be given loads gradually and not forced to carry heavy loads before the age of six. Riding camels should not be struck on their necks, rather they should be struck behind the right leg of the rider. Leese described two types of saddles generally used in camel riding: the Arabian "markloofa" used by single riders and the Indian "pakra" used when two riders mount the same camel.
