Another problem with Bull..LOL Just kidding!

Your crate should be big enough for him when he is grown up...so that he can stand up turn around and lie-down easily...thats why you need to put a blanket of some sort where he lies and just in case of accidents put a puppy pad in there or just leave one area with nothing on it...that way if he goes its not bad but, its also easy to clean up..hope this helps!
