Extreme weather doggy door suggestions

[212david51]

PetSafe Extreme Weather Dog Door. TWO flaps, one on the inside of the house, one on the outside. Both have magnet bottoms that really hold them closed. The flaps are flexible to some extent but heavy. With two heavy flaps and the magnets it does not blow open even in a strong wind. If you have a wall that is thick you can get a sleeve that will connect the two sides making the door into a six to 10 inch long tunnel thru the wall.
