Sheepdog training. My theory on flanks and a practical round pen training session

I have been working on Ralfs sides but he is slow about learning them. The reason is, as I see it, is that he doesn't want to let go of his hold on the sheep. Ralf has lovely balance and feel for his sheep wants to be at the point of balance all the time. I need to get him to let go of his contact on the sheep .. and flank when I ask him.
