Agility is a dog sport in which a handler directs a dog through an obstacle course in a race for both time and accuracy. Dogs run off-leash with no food or toys as incentives, and the handler can touch neither dog nor the obstacles. Consequently, the handler’s controls are limited to voice, movement, and various body signals, requiring exceptional training of the animal and coordination of the handler.
In its simplest form, an agility course consists of a set of standard obstacles laid out by a judge in a design of his or her own choosing in an area of a specified size. The surface may be of grass, dirt, rubber, or special matting. Depending on the type of competition, the obstacles may be marked with numbers indicating the order in which they must be completed.
