Petmate Indigo Dog House Door (XL) – A clear, flexible vinyl flap door designed to fit the Extra-Large Petmate Indigo igloo-style dog house. It attaches above the doorway and hangs down to help shield your dog from wind, rain, and cold while they’re inside the dog house. The flap is heavy-duty but allows easy in-and-out access. Installing this door can significantly increase your dog’s comfort in extreme weather and gives them added privacy. It’s easy to clean and can be removed in mild weather if preferred.
