Dogs feel pain differently than we do I would assume.

Also you stepped on the pad with your bare feet?

Plexi glass. Find a way to put it on the door (glue, as little screws as possible) and it would take a long time for the dog to destroy it. You only need as much plexi glass on the door withing his reach.

So say when you move, if you use glue it can be washed off (take some work) if you use screws (say 4) you can fill the holes and paint over it.

Trust me the little work it takes to fix plexiglass after taking it off is alot simpler then fixing deep scratches that might always show even with fill.

Good luck.
