Editor's Pick: Once fall arrives, nights get chilly and drafts blow through the dog house doorway, making dogs curl up in a ball inside. This clear PVC door flap blocks wind and rain without blocking light, and dogs can push it open themselves going in and out. Installation is simple—all hardware is included, just screw it onto the inside of the door frame. Measure your dog house opening before ordering to make sure it fits. The plastic material is not bite-resistant, so keep an eye out and check it regularly if your dog likes to chew.
