In its simplest form, an agility course consists of a set of standard obstacles, laid out by an agility judge in a design of his own choosing on a roughly 100 by 100 foot (30 by 30 m) area, with numbers indicating the order in which the dog must complete the obstacles. Courses are complicated enough that a dog could not complete them correctly without human direction. In competition, the handler must assess the course, decide on handling strategies, and direct the dog through the course, with precision and speed equally important. Many strategies exist to compensate for the inherent difference in human and dog speeds and the strengths and weaknesses of the various dogs and handlers.

Competition Basics

Because each course is different, handlers are allowed a short walk-through (also called a run-through) before the competition starts. During this time, all handlers competing in a particular class can walk or run around the course without their dogs, determining how they can best position themselves and guide their dogs to get the most accurate and rapid path around the numbered obstacles. The handler tends to run a path much different from the dog's path, so the handler can sometimes spend quite a bit of time planning for what is usually a quick run.

The walk-through is critical for success because the course's path takes various turns, even U-turns or 270 degree turns, can cross back and on itself, can use the same obstacle more than once, can have two obstacles so close to each other that the dog and handler must be able to clearly discriminate which to take, and can be arranged so that the handler must work with obstacles between himself and the dog, called layering, or at a great distance from the dog.

Each dog and handler team gets one opportunity together to attempt to complete the course successfully. The dog begins behind a starting line and, when instructed by his handler, proceeds around the course. The handler typically runs near the dog, directing the dog with spoken commands and with body language (the position of arms, shoulders, and feet). Because speed counts as much as accuracy, especially at higher levels of competition, this all takes place at a full-out run on the dog's part and, in places, on the handler's part as well.

When all competitors have run, scoring is based on how many faults are incurred. Penalties can include not only course faults, such as knocking down a bar in a jump, but also time faults, which are the number of seconds over the calculated standard course time (SCT), which in turn is determined based on the competition level, the complexity of the course, and other factors.

Training

Before you can begin Agility Training, your dog must be able to perform Off-Lead skills perfectly. Teaching a dog the basic execution of most obstacles takes only a small amount of time and simple training techniques; most dogs can be readily convinced to run through a short, straight tunnel to chase a toy or to go to their owner, for example. However, to compete in agility trials and to develop speed and accuracy, both dog and handler must learn a wide range of techniques for doing the equipment, performing sequences of obstacles, and communicating on course while running full out.

The teeter-totter (or seesaw) and the weave poles are the most challenging obstacles to teach, the first because many dogs are wary of the board's movement, and the second because it is not a behavior that they would do naturally over a series of 12 poles. However, it can also be challenging to train the dog to perform its contact obstacles in a manner that ensures that they get paws into the contact zone without sacrificing speed. Training techniques vary greatly. For example, techniques for training the weave poles include using offset poles that gradually move more in line with each other; using poles that tilt outward from the base and gradually become upright; using wires or gates around the poles forcing the dog into the desired path; putting a hand in the dog's collar and guiding the dog through while leading with a toy or treat; teaching the dog to run full speed between 2 poles and gradually increasing the angle of approach and number of poles; and many other techniques.
