Query: not good for climbers

This is a great little dog play pen. I purchased this to keep my 7 lb. yorkie in it during the work day. It worked great until he figured how to climb over it. I would recommend this if you have a dog who cannot jump very high or doesn't know how to climb out. I was able to rig a little cover for it to keep him in and it suits us fine now. It's perfect for inside use and a better option than crating your dog all day long.
