I don't recommend buying it!
Scam. They advertise it as an insulated dog house, but there are 3-5 mm gaps between the floor slats, and it's not insulated, just like the side walls and the roof aren't insulated either. You can screw a heat shield onto the entrance, but that doesn't make the house insulated. The dimensions shown are not the usable ones; it's much smaller than advertised. For dogs where the ridge height is suitable, the low side wall height means they can't turn around, and for those where the side wall height is good, they can't keep it warm because of the ridge height.
