Rosie is a chewer. I have never had a dog that chewed. Chloe has the same baby that she got when we first got her. We hid it on Rosie because she destroys everything. Zoey has never chewed anything either. I'm not even sure when she does this stuff...but she does.
Only thing I can think to do is keep her confined to one room when no one is around...or buy her a case of chewies.
