We ordered the largest possible size for our English mastiff puppy. Love that it has a puppy partition! For the price, I'm thrilled with the crate. I took off a star bc the metal pan at the bottom doesn't lie perfectly flat and is quite loud when you push on certain parts of it. But lots of blankets on top seems to have mostly fixed the issue. Also, the sides are very slightly bowed, which makes the latches line up a little askew from each other. Again, a little finagling solves the problem. We're very happy with our purchase.
