I can't really complain about any of my animals being destructive these days. The cats used to push things off tables and shelves and broke a few things that way but nothing more serious than that. Bella has gotten over most of her naughty puppy ways but will still shred and dismember her stuffies in record time. At least she is ruining her things these days and not mine! One of the worst things she did was rip wallpaper off the wall! She found the tiniest little edge close to the molding that wasn't glued down all the way and pulled on it with her teeth one day when I was on the phone. Fortunately the paper is vinyl and it was pretty easy to repair. She also chewed a hole out of the corner of the carpeted stairs while still a puppy to.
