I have an alley that I can work Chris in. I have not really utilized that area for training, but grazed the sheep out there from time to time, and I saw the strong draw back to their normal pasture, so I tried some training in there.
It worked for the sheep trying to bolt away senario, and sending Chris to cover. At first she was hesitant, and with encouragement, and a little time, she is somewhat willing to go either direction, with the sheep moving either west or east.
It has seemed to boost her confidence, and at the same time, she has to really move quickly, so they do not escape her as she passes them. This alley has turned out to be a good tool for her. I will train a little more in that area.
