How to stop 4 month old puppy from peeing in crate? & problems with housebreaking?

We have had some time trying to get our new puppy potty trained as well. He has gotten 99% better. The things that I started doing is watching when he ate, drank, played or got up from a nap. I would then take him out to potty. As soon as he would squat I would start praising him...saying good boy and when he finished I would give him a treat. As far as him using the potty after it's bed time. about an hour before we go to bed, we put his food and water up that way he can't eat or drink anything an hour before bed. Then right before we go to bed we take him out to potty before we go. He does wake us up during the night/morning hours to potty. At first I tried him and rubbing his noise in it or telling him bad boy if he peed where he is not suppose to, but that only made it worse. I started to ignore it and not say a word to him or do anything to him and just clean it up, and then is when the accidents got alot better. I'm not saying he is 100% better, cause he still has an accident every once in a while, but very rarely. Confine him into a smaller area wher eyou can watch him, that way if you see him start sniffing alot he's gotta potty. I hope this helps you...Good Luck!!
