I am very happy with The Original Pet Gazebo. It was delivered in two separate boxes which was unexpected. It was very easy to put together. It only took about an hour for one person. The large size is plenty big enough for a full grown golden retriever (not full time of course). It's very heavy and sturdy. There is plenty of room to stand inside. There is a small door that opens for easy feeding and watering. I think this would make a fantastic chicken coup was well!
