Our Siberian Husky loves his nighttime bed place.  It is very sturdy including the flooring which gets quite a nail/scratch workout by our energetic husky.  We've had this product in constant nighttime use for 10 months now and it seems just like new.  It is also helpful having both doors available.  We have since purchased a 2nd one that our family sets up when we come for a visit, but can store easily when not in use.
