I believe you are the one who should be punished for not watching your puppy! If you can't be within grabbing distance of your puppy, paying attention to what she's doing, then she needs to be confined in some way someplace that she's safe. Also pick up/put away as much stuff as possible that she might like to chew. Anything my puppy has destroyed was our fault for leaving it within puppy reach, and/or not supervising sufficiently.
