I guess I should clarify. What kind of insulation would a dog not chew up? They are only in the backyard a few hours in the day but are finishing up their teething.

You can use any insulation you want, just sheet over it with OSB or plywood.

they sell double walled plastic doghouses (similar to a cooler's construction) for likely cheaper than the material to diy
