What is Working Cowhorse?

source: Wikepedia

In Working Cowhorse, the horse is required to perform two different sorts of work. One session consists of reining work, where a reining pattern is performed. This is often referred to as the "dry work." The other is the cow work, where a single cow is released into the arena and the horse is asked to first hold the cow at one end of the arena (known as "boxing") then run the horse along the rail of the arena, turning it back without the aid of the fence (known as "fencing"). Lastly, the horse maneuvers the cow into the center of the arena and cause the cow to circle in a tight circle in each direction (known as "circling"). The horse is judged on the ability to control the cow, as well as speed, balance, responsiveness to the rider.
