Question for you -- one of the people at work recently got a puppy (they named it pat-pat which apparently means bum-bum in Chinese because it's a pomeranian/maltese and has a cute butt) and wanted to know if you can buy something like a thin clear sheet of plastic to stop the dog scratching it up. Any ideas?? I don't even know if layering the door with multiple coats of varnish or polish etc would work either.
