All tagged Bits
The mouth of a Thoroughbred is the principle means of communication between the horse and his rider. Other aids are used as well, but for many, the bit is what determines direction, rate of speed and position or frame in which the horse moves. The design and function of the horse’s mouth is such that it provides a perfect vehicle for use as a “steering device.” The interdental space allows a bit to lie comfortably without interfering with the normal position of the jaws when they close. Horses are the only domestic animals that have their mouths used in this fashion.
