I purchased this crate from Wayfair about a month ago. It is a great size for my mid-size puppy (almost 40 lbs). She has plenty of room to stand and lay down. My only problem has been with the door latches. They are very hard to slide open and closed. It may be because it had been a returned item that I purchased through the clearance center. Maybe the latches are slightly bent from assembly, disassembly, and shipping? I cannot tell. But I would recommend this crate for a mid-size dog.
