The exit of the weave poles now has to be at least 12 feet from the edge of the ring (the fencing). Thank goodness! I know some dogs have problem weaving into a wall.
It used to be that if a handler knocked over a stanchion, you would NQ. Now it's if *either* a dog or handler knocks a stanchion, the team NQ's.
Finally, if a handler wants to change the score to NQ their dog, they may. For example, if you know your dog popped at #10 in the weave poles but the judge didn't see it or call it or the scribe didn't record it, you can correct the score and have your team NQ'd. Good news for the few honest people left in the world, eh?
