Instead of keeping all your doors closed to keep dogs (or people) out of bedrooms, purchase plastic lattice at your local home improvement center. It comes in different colors. Cut approximately 12 inches longer than the door way is wide and place inside doorway. Or use it to temporarily block off a staircase (not for solid use).

I am thinkilng, wouldn't it be easier to just buy and put up a baby gate. This is what I use to keep the dogs downstairs.
