Protect your doors from scratches
Protect your doors from your dog's claws with a sheet of plastic. Buy 1/8-in. or thinner Plexiglas or plastic at any home center. Cut the Plexiglas so it fits just inside the door jambs and is 1 ft. higher than the reach of your dog. Most home centers will cut the Plexiglas for you, but you can also cut it with a utility knife and a straightedge. (If you have a large dog and need plastic above the doorknob, use a 3-in. hole saw to make a cutout for the knob.) Mount the Plexiglas to the door with 3/4-in. roundhead wood screws.
Tip: Mask shallow claw marks and scratches in wood doors with stain and varnish. Gel stains work well for matching the existing finish.
