This might actually be a good place for women's tears. Maybe a good loud scream of terror or pain when the dog jumps on her. (Though I don't know if an untrained dog [or one trained to jump on people in excited greeting] is likely to react violently to screaming.) I understand the shocked impulse to freeze and try to act like you're in control of the situation. To think in terms of "I might have been attacked" rather than "I was just attacked." But that illusion of control makes it easier for other people to ignore what just happened, to not take it seriously.
