I agree with Doc. Kennel the dog when you are not with it. If you do catch her chewing something that is not hers calmly grab her by the back of the neck and give a little shake and say "Thats Not Yours" in a commanding voice and give her a toy that is hers. You must be prepared at all times for this. It is worse than raising a child, lol. This is the same way the mother dog would discipline her. Good kuck...
