"Agility is a sport that is designed to demonstrate a dog’s willingness to work with its handler in a variety of situations. It is an athletic event that requires conditioning, concentration, training and teamwork. Dog and handlers negotiate an obstacle course racing against the clock. Agility is one of the fastest growing dog sports in the United States and the fastest growing event at the AKC. Dogs of all sizes can compete in agility, the dogs all run the same course with adjustments in the expected time and jump height. Cocker spaniels are one of the most popular breeds competing in AKC agility." -The American Spaniel Club, established in 1881.
