Flyball is one of the non-hunting dog sports in which dogs and people work as a team. Many casual pet owners use their flyball time more as a way to relax and socialize with other dog owners than as a competition, and many champion flyball dogs are essentially pet dogs with a hobby, rather than dedicated sporting or working dogs. On the other hand, modern flyball has become the fastest-growing team sport, a sport for dogs, handlers and coaches. First division teams have well-trained dogs and handlers and are trained and coached to perform. Some teams use dedicated specially bred sport dogs.
