When she's chewing on something she shouldn't, give her a toy that she CAN chew on as a trade. Kongs are worth the investment. Or try a cow hoof. They are inexpensive and last a long time. They don't smell very good, though. Nylabones are pretty good, too. I wouldn't give her rawhide, though. It's less expensive than a kong or Nylabone, but they stink, get slimy and can get caught in her throat.
