Belle loves paper, any kind of paper. My DH leaves his magazines down and it is so fun for her to start on one of those. Once in a while she'll come running out of the bathroom with a long stream of toilet paper following her. It's hard not to laugh sometimes because she knows she's being naughty. When I finally get close to her, she jumps up on the couch and sticks her head down between the cushions to hide leaving her little butt sticking up. I had a hard time trying to figure out where she was getting a book once in a while. We got a new couch and I didn't realize the back of it was so close to the book shelf. Belle was eating a book called "NO Bad Dogs"
My Minature Schnauzer was the same way with paper. I think Belle does it because it's fun and she knows I'll probably chase her and she loves that.
