They are pack dogs, they will have to " accept you" into their pack. Take your time, she will trust you! :)
just show her that your harmless and loveable, try acting like a dog around her and show that you wont hurt her, be a friendly puppy!!!
Food! Control the food and you make a massive step toward pack leader. Use treats for rewarding her when she is positive and you will soon find her accepting, and more importantly respecting you.
