LOL my rottweiler liked bitter apple too! She used to chew through walls though so not much stopped her. But Kaos didn't chew anything in his life that wasnt his...soo I'm not too much help.
If he had been a chewer and I was in your position, I would probably try a squirt water bottle, followed by a "no" and if she continued I would put her in a short crate time out. When Kaos did something I didn't like thats what I did. He knew if he didn't want to be crated not to do those behaviors, and he picked up on it fast.
