A very useful technique to widen your dog's flanks.
WHY NO VIDEO?
One of the best ways to get a dog to give the sheep space when it's flanking is to use a technique we call "sending the dog the wrong way". Once you can achieve this, you and your dog are well on the way to producing quality work - but it's not easy.
As with so many other aspects of sheepdog training, once you understand why the dog is reluctant to go "the wrong way" it becomes much easier to train it to do just that, and the dog's flanks will widen out.
