This pen is great for our small dog (5-10 lbs)! It's easy to assemble and easy to clean. Our dog had one scare where he wrapped his mouth around two vertical bars and got stuck, but the bars are a pliable and we were able to get him loose. He hasn't tried to do that since and it's become his favorite place to relax and eat his food. It doesn't have any sharp edges and he's not able to bite the wood supports.
