Well, it is very well known that rubbing their noses in the mistakes doesn't do anything as far as learning, if anything it creates a wall for building a trusting relationship. TThe advice I can give you use start to let her go outside and try treat training. Everytime you take her out say POTTY firmly constantly until you see her do what she is supposed to and give her a treat and praise alot. After a week she will get it and will do her thing just to get a treat. This is what worked for me. Now you must take her out every 3 to 4 hours otherwise they ahev no choice cause they can't hold it that long. I really pad training might not be the best because even if she intends to use it, it isn't being done properly and you end up having to clean and that's why you are getting frustrated.
