Even if you don't recognize it by name, you have probably seen an agility competition. Designed to demonstrate a dog's willingness to work with his handler in a variety of situations, agility is an athletic event that requires conditioning, concentration, training, and teamwork. Dogs and handlers must negotiate an obstacle course while racing against the clock. Agility is a great form of exercise for both dog and handler, and a fun way to bond. And you don't have to compete to enjoy agility. Taking an agility class offers many other benefits. But many people start the sport just for fun, only to get bitten by the agility bug and become lifelong competitors!
