ASL Solutions deluxe small dog house features 1.5" to 3" of real Styro/ESP foam on the walls, floor, ceiling and door.  The door is self closing and the lower panel has a window so your dog or cat can see out while resting comfortably.  The rear panel also has a window that is removable without tools.  These windows are self storing and provide excellent cross ventilation when they are in the summer position.  The floor is sloped with a drain for easy cleaning.  The house also has a heating blanket (purchased separately) which plugs directly into an outlet.
