When you first get your pup home, try to get him used to the crate gradually. Teach this as often as you can the first day. You can gradually taper off the training when he is willing and eager to get into his crate, and lays there quietly to chew on a bone when he's inside. This will take several days. First few times, put a treat in the crate and let him go in to eat it. Leave the door open and praise when he's inside. Do it again every few minutes. After a few times, close the door when he's inside and feed him treats through the wire, praising while you do. Keep feeding all the while he's in the crate. After you've given a few treats, open the door and let him out. Don't make a big deal over him when he comes out. You want being INSIDE the crate to be the fun part.

After he's getting used to this and going into the crate willingly, toss a treat into the crate to get him to go in, close the door, stand back and count to three, then give him a treat through the wire. Repeat the count and treat several times before you let him out. If he cries when you step back, say "no" in a non-angry tone, look away, and wait for him to quiet before giving the next treat. Don't move toward the crate while he's crying, but the moment he stops, step up and treat.

Next, do the same as before, but count higher, to 5, then to 10, then to 20, etc...
Put the pup in the crate with a tasty chew toy, like a flavored rawhide. Let him out as soon as he's finished, but NOT when he's crying to get out. When the pup cries to get out of the crate, say "no" and wait for him to quiet before letting him out.

THE FIRST NIGHT

Try to feed and water your pup earlier in the evening, not right before bed. The first night, I like to put the crate right beside my bed, so I can dangle my arm over the edge of the bed to pet the pup through the wire. I only pet while he's quiet. Some people say a clock ticking nearby will help, or a water bottle filled with warm water inside the crate, but I haven't had much success with these. I always put a nylabone in the crate with the pup, and rub it between my hands good before I do, to put some of my scent on it. If it doesn't gross you out, you can spit on it and rub it in a little before you give it to him. Dogs love people food, and this will probably convince him that you value that bone. You may want to try a rawhide chew bone instead. Most dogs like these better at first, but the rawhide isn't very good for them in large quantities.  Be sure to take him outside right before he goes to bed. Watch to make sure he relieves himself. Then you can be pretty safe in assuming he doesn't need to go the bathroom for at least an hour or two.

When he cries at night (notice I didn't say IF) just tell him "no" in a matter-of-fact sort of voice and ignore him while he's crying. If this doesn't work and he continues to cry after a minute, I'd try a louder, angrier "no". Say it just as he is STARTING to cry. If the angry "no" doesn't help after a few times, just ignore him for 5 minutes or so. Then try again.

If the pup cries constantly for an hour or so the first night, I would take him outside again, in case he needs to relieve himself. Try to pick a time when he is quiet to make that initial move toward the crate, so he doesn't think he's being let out for crying. Praise him softly and put your hand down by the crate when he's quiet. If you want him to sleep in the crate, try not to break down and let him out to sleep with you the first night. That first night in the crate doesn't get any easier with time. It seems to be harder to resign a pup to sleeping in the crate once he's learned that there are other options. The bright side is that the second night is much easier. And by the third night he will probably settle right down to chew on his bone or sleep with hardly a wimper.

If your pup finally seems to settle down and go to sleep only to wake you up again after an hour or so, take him out to relieve himself. You may have to do this every 2 to 4 hours until his bladder grows enough to hold it all night. I've found that pups can sleep through the night by the time they are 4 to 6 months old. But as long as he's waking you up crying, take him out. Just make sure it's only a bathroom break. No playing, and right back in the crate when he's done. (Of course praise him profusely for going to the bathroom outside first.)
