I have been looking for these dog houses forever and finally am able to share them with customers. These dog houses are white solid fiberglass. White to reflect the sun and stays cooler in the summer. And then the fiberglass insulates the top, bottom and sides!  The dog house roof has a two inch slant to the back – helps keep the dog dry and then the roof is hinged for easy cleaning or extra ventilation or at times to look at the puppies.
