This kennel is really sturdy and well made. Only thing I don't like is the plastic tray on the bottom doesn't support a big dog and we've had to replace it twice. The base of the kennel is about 3-4?? off the floor. For reference our dog is a Bull mastiff and weighs about 90lbs. The kennel size is perfect for her. The kennel we bought was lost in shipping and the company was amazing to work with. They sent us another one, I would definitely buy from them again!!
