My dog isn't trained enough to not go through a door, especially when a chipmunk runs by! For our two week vacation that just ended, I rigged a plywood board just taller than "jump" height that can either go inside or outside, depending on the dog's present location. It's a PITA for us humans when going in and out frequently, but it does the job. I'm toying with adding one of those "Magic Mesh" magnetic screens eventually.
