Sheepherding is a ballet in a way, an ancient dance. Zelda is a difficult sheep, tough and independent and she knocked Red down when she first saw him (me too, several times). Red has been quietly challenging her ever since, never touching her or charging her but meeting her very strong gaze head on. Border collies herd with their eyes, and when Red locks onto Zelda, I feel as if I am suddenly a witness to a drama almost beyond my comprehension. Red is a very professional dog, very appropriate. But he is very strong, he does not back down or quit. Zelda does not try and knock him down any more, and now when she sees him, she runs to hide behind me.
