This is a sturdy dog pen suitable for large dogs. As shown in images 5 and 6, some parts are missing. If you are concerned, please use zip ties or similar to secure it. I have been using it as is. There were no particular problems. The dog breed was a Border Collie. There are scratches and dirt from use, so please refrain from purchasing if you are at all concerned.
