I absolutely love this piece and my dog does too. It looks so much better than the wire crate I had before. She goes in on her own to play or lay down. Unless we’re leaving the house, I leave a door open so that she may go in and out as she please! The box was really heavy, around 100 pounds. The instructions were really easy to read. I was able to put it together on my own in about an hour. However, I did have my son hold a couple of pieces in place so that I could lock them in. My dog is about 60 pounds and really short. Thankfully she does not chew on things because it’s wood so I’m not sure how durable it would be. She has a lot of room inside. Some times my 7 year old climbs in there with her when they are playing and there is still plenty of room. We all love it and I would definitely recommend to others.
