Crufts flyball is more a fun thing for the spectators at Crufts, as it is the most popular "exhibition" at Crufts and it draws the crowds.
No one gains any points, and handlers and dogs can be from various BFA teams. Crufts is Crufts, and by competing at Crufts you get free tickets for the show and you can take your dog(s) with you.
(and see yourself on the tele
I heard (don't know if it's true or not), that the rule for dog's changeovers were changed during the racing at Crufts from crossovers at the posts, (nose to nose as in BFA racing), to coming-back dog's whole body through the posts before going-in dog goes through the posts.
Peter Purvis alas, has never tried to learn what flyball is about, and every year makes stupid mistakes, either concerning the racing, the results, names of teams and where they come from, to the breeds of dogs running. Why can't they have a BFA member doing the commentating? There are some very good folks out there who have commentated during BFA racing at public venues.
It also shows people what flyball is and that if they have a dog, they can go try it out at a local club.
