I think there's some kind of spray or something that tastes horrible to dogs, made specifically for this problem. Just pray some on whatever she's chewing up, and maybe make her toys a little more enticing. Maybe take a bite of leftover beef or something and rub it all over to give it the flavor and the smell.

I assume that such a spray wouldn't be in any way harmful to her besides tasting like hell, and that you wouldn't be bothered by it (smell, etc.), either.
