Agility is basically an obstacle course for dogs. The object is to get your dog to go through a series of obstacles quickly and correctly. These obstacles include the A-frame, dog walk, teeter-tooter, tunnels, suspended tires and, of course, jumps. Each agility course is set up in a different configuration. Agility was invented in 1979 at Cruft's Dog Show in England as entertainment for spectators. Since then, it has grown into a very popular dog sport.
