Roxy chews real bad too. I can say that all the dogs I've ever had always grew out of chewing in a few years. I always keep chew toys and fresh rawhides available to her. It seems to help. We have had to fence off all our plants and trees though. We don't leave anything we dont wan't destroyed in the backyard with her. She isn't really allowed in the house much right now. You have to totally have your eyes on her. If you turn your back for 20 seconds, she has something in her mouth.
