See for yourself why the Gun Dog House Door® Heavy Duty
and Big Dog Pet Door are the best! These dog doors are the only two-way dog doors on the market with "special" heavy-duty spring loaded hinges that provide a positive weather seal! When your dog goes "out" the door, the inner clear plexiglass panel and the outer welded aluminum frame move. When your dog goes in the door, the welded aluminum outer frame stays stationary and only the inner clear plexiglass panel moves.
