This is great for our 21-lb. Cocker Spaniel.  The two sliding doors operate perfectly and the crate won't take up more room than necessary when the doors are open.  The crate is well made and has a removable tray on the bottom.  There are two additional features not found on many other wire crates:  stability corners and rubber feet.  Although the manufacturer initially sent the wrong size item (small instead of medium), the helpful Wayfair customer representative helped me place a reorder.  If the manufacturer doesn't want the first one returned, our local Cocker Spaniel rescue will get a donation!
