Why it's at #6? We put this Midwest Life Stages Single-Door Folding Metal Dog Crate as sixth on the list of best extra large dog crates because several customers had issues with it collapsing, though whether this was from human error or because of faulty conditioning, they weren’t specific. But, when it comes to housebreaking, the dividers in this are very useful.
I love the size of this crate and the tray on the bottom it's a great thing to have when a "time out" needed. However, we experienced some of the same problems as others; puppy tearing it apart because of small gage wire, welds not holding, needing to use zip-tries to hold the walls together and problems opening the door latches - this is why it received 3 stars for this review. My husband called the company and they readily fixed the issue without a hassle or argument; the company itself gets 5 stars for their customer service.
It sure is a good thing I checked amazon.com for dog creates before spending almost twice as much at a major pet store! This crate is perfect in every way. It's very well made and the price can't be beat. The bottom plastic tray can be easily removed for cleaning and the crate collapses very easily. It's pretty easy to open and close with the double sliding locking mechanism, and it comes with a partition so it can grow with your puppy. I can't imagine housetraining our now-five-month-old puppy without it! We love this create, and so does our puppy.
