I have four dogs and a brand new door. Unfortunately I have one dog scratching the door to get out and another to get in. Plexiglas was easy to cut with a carpet knife. I attached it to the door with double sided transparent tape with polka dots. Plexiglas is quite light, two points on each side are enough. I also attached one to the outside of the door. It's hard to say. Very happy with my purchase.
