The shepherd doesn’t run after the sheep when they get straying; he shouts to his dog, and the dog runs after them, barking at them in a very rude way. When you see a sheep dog doing that, it ought to remind you of my sermons; you should think of the clergy yapping at you and saying, “You ought to do this,” and “You mustn’t do that”; they do it because they are acting under the Shepherd’s orders. I don’t say the clergy don’t sometimes enjoy it; but then, I dare say the sheep dog enjoys it.
