Herding is an interesting leaning curve. Using a dog to take 3 head of Shetland sheep through various obstacles at different designated angles is always different each and every time. Here is a photo from our 4th of July AKC trials. This is Anna putting 3 head easily into the opening of the Y chute. She is allowed to follow/push them through the obstacle but me the handler is not allowed to go into the obstacle to lead the sheep through. This is a very nice clean entrance with no points lost.
