You need to be more firm with her. She's not getting the idea that biting is not okay. Odie was the worst nipper in the world, and the squirt bottle also did not work with him. When he would bite, I would gently put my hand around his snout, push his head down, and give him a very firm "NO". Then I would redirect him to his toys to chew on. For the most part, he grew out of it, but the command worked as well.
