Crate her when you can't watch her. If you catch her chewing something she shouldn't be chewing, discipline her. I usually just give a stern look and say "No! Bad pup!" It seems to work.

I, personally, wouldn't give rawhide though. It's filled with chemicals and often leaves film on their teeth, allowing plaque to build up. There are some great natural alternatives. My dogs LOVE bully sticks. They're.. an odd concept (to say the least) but my dogs go crazy for them. It keeps them nice and busy too.

Don't worry, you could still get her to sleep with you after she gets over her chewing phase. I crated Kai until he grew out of his puppy habits. He now just sleeps wherever he pleases.
