Hi welcome to Pet Talk.

Like Karen said the situation isn't hopeless and there's bound to be people on the board who can give you some helpful info but we do need some more info Karen covered all of it.

As for the flipping her on to her back thing, opinions varies on this one. I wouldn't do it personally because I believe that there are kinder, gentler ways to establish your self as the alpha member in the pack. In fact sometimes flipping the dog on the back could just add to the problem.
