I ordered one in pink and one in blue.  It came with an extra piece for puppies being crate trained, but I didn't use it.  My pups are both adult dogs and love sleeping in their crates.  My mini dachshund sleeps in the blue one.  Unfortunately, the lever to lock it is really hard to close on his.  I think it must of got a bit bent in shipping, but not worth sending back.  My chihuahua mix sleeps in the pink one.  It works perfect and the lever closes on it just as it should.  Since they are both such small dogs, I've actually at times stacked these condo style.  They are sturdy and I felt comfortable enough to keep them in there stacked.  I would recommend these to anyone that has a small to medium dog.  Plus the colors are just too cute to pass up!
