Controlled chaos! Drag racing for dogs! These are some of the phrases used to describe flyball—a relay race for dogs and their humans.
Flyball began in the 1980s as an offshoot of scent hurdling (a sport that was itself started in the 1960s). In scent hurdling, a team of four dogs and handlers races against other teams. The object is to see which team can be the first to send all their dogs over four jumps to retrieve scented dumbbells and return with the correct dumbbell.
