Flyball is a team relay race for dogs!  The course consists of four hurdles spaced ten feet apart with a start line six feet before the first jump and a flyball "box" fifteen feet from the last jump.  Each team, consisting of four dogs, race one dog at a time over the hurdles to the box where the dog must catch a tennis ball and race back over the hurdles before the next dog is sent.  
Flyball is a fun, fast paced game that dogs LOVE.
