Perfect for any backyard, this house is just the right size for small or medium breeds. The backyard house is constructed of heavy-duty, weather-resistant plastic. This material is non-absorbent, and won't fade, crack or deteriorate over time. The roof is removable so cleaning the inside of the house is easy. The thoughtful design of this house ensures your dog stays warm and dry all year. The floor slants downward all around so water can't make its way inside and a rain flap over the front door protects your dog against blowing winds and rain. Assembly is super easy. Just slide pieces into place and lock them into position.
