Flyball is an exciting fast fun sport for people and dogs. Flyball starts with two racing lanes, each with four jumps spread over 51 feet to a spring load box holding a tennis ball. Add four dogs, each racing down the lane individually hitting the box which activates a lever to eject the tennis ball. The dog grabs the ball, races back and the next dog takes his turn, passing the returning dog at full speed. This all adds up to lots of noise, lots of excitment, lots of fun, and lots of very happy dogs and handlers.
