I would give her a verbal like "aagh!" and then perhaps make her sit. I guess it depends on what you need her to do. She should respect you as the boss as well as any one else. You also need to be calm.
There is a Cesar Milan tape that deals with training a border collie on a farm. I just dont recall what season or episode it was.
As a start though try the "aagh" and sit you may find it helps!

"UNTIL ONE HAS LOVED AN ANIMAL, PART OF THEIR SOUL REMAINS UNAWAKENED"
He is your friend, your partner, your defender, your dog. You are his life, his love, his leader. He will be yours, faithful and true, to the last beat of his heart. You owe it to him to be worthy of such devotion.
