Indy has a "Large" size wire crate from walmart. We decked it out with a king size comforter, two fleece blankets, and a life size "puppy" stuffed animal. Then we throw in a deer antler and two of his favorite stuffed toys and tell him to have at it. So far no problems. The other cool thing about this crate is that dh made him a "deck" ontop. We put the kennel next to the couch so he can climb up the top and onto the deck. He hangs out there and looks out the window all day long sometimes.
When he was younger we put the divider in, but once he showed us that he knew pottying in his crate was not ok we just let him have all the room. So far so good.
