The Dog Palace CRB Palace Premium Insulated Dog House will help keep your dog warmer during the winter and cooler during the summer. Sized for extra large or multiple dogs, the insulated dog house features 100% recycled insulation in every panel, a self-closing insulated door, a raised sloped floor for easy clean-up, and repositionable windows for summer cross ventilation. This dog house is also twice the volume of the original Dog Palace.
