Flyball is a team sport for dogs that was invented in Cali-
fornia in the late 70's. Legend has it that Herbert Wagner
first showed it on the Johnny Carson Show to millions of Americans.  Soon afterwards dog  trainers and dog clubs
were making and using Flyball Boxes.    In the early 80's
the  sport became  so popular  that  the  North American
Flyball association (NAFA)  was formed and they are the worldwide authority for Flyball.

Flyball  is a relay race with  4 dogs on a team. The course consists of a  starting line, 4 hurdles  spaced 10 feet apart
and a box.  The first hurdle is 6 feet from the start line and
the box is 15  feet from the last hurdle  for a 51 foot overall length.   The dogs jump the hurdles and steps on a spring loaded box that shoots out a tennis ball.  The dog catches
the  tennis  ball  and  then  runs  back  over  the 4 hurdles. 
When the dog crosses the starting  line the next dog goes.  The  first  team to have  all 4 dogs run  without errors wins
the  heat.   Tournaments are usually  organized in either a double elimination  or round robin format.  Double  elimina-
tion is usually best of 3 or best of 5.Round robin is usually best 3 out of 5 and the first team to win 3 heats receives 1 point towards their standing in the tournament.

The hurdles height is dependent on the shortest height dog
on the team.8" is minimum and 16" is maximum.
