Before you bring him home...
Ideally, set up a small room or corner to be his very own "place" for the next couple of months. Paper the entire floor and put his food/water bowls and bed or crate in one corner. Put his toys on the floor.

Decide who will be responsible for feeding and cleaning up after him and stick to it for at least the first few weeks.

The first day...
If at all possible, pick up your puppy at a time when you will be home for a few days. Try to get him home in the morning or early afternoon. This way he'll have all day to adjust and get to know you before that terrifying and lonely first night away from the rest of the litter!

When you get home, put him on the ground to go the bathroom before you bring him in the house.

Let him explore the house and figure out where he is before trying to play with his.
Play with him quietly and gently. If he looks like he wants to sleep, leave him alone. Like babies, puppies need lots of sleep. They play hard and sleep hard!

Don't take your puppy anywhere for the first few days, except perhaps to the vet. He needs a little time to get to know you and your house before exploring the larger world.

The first night...
As it gets towards bedtime, wake him up to play if he's asleep during the last hour. You don't want him napping all evening and getting wound up again right at bedtime. Don't offer him any food or water after about 7 pm.

Just before bedtime, take him out to the bathroom, then calmly put him in the crate. Be sure he has his special blanket or toy if you brought one from his litter. If possible, put the crate next to your bed so he knows you're there. If he cries, you can put your fingers through the door to reassure him, but mostly just be matter of fact about it and ignore him. Don't talk to him and especially don't let him out! He'll settle down and go to sleep.

During the first few months, he will probably not make it through the night without a bathroom break. If he wakes you up crying in the middle of the night, take him outside. Dress or put on your robe quickly before you open the crate, carry the puppy to his bathroom area immediately, praise him quietly when he performs, and then bring him back in and put him in the crate again. Don't let him get you involved in a play session or you'll be up for a couple of hours! Turn out the lights and go back to sleep. He may whine, but don't let him out. Just put your fingers through the grate and let him know you are there, but it's still bedtime.

Be patient. The first few nights are always the worst!

A few additional tips...
Try to limit visitors for the first week...it's going to be confusing enough for your puppy!

Set rules from the beginning. If he's not allowed on the good sofa, don't put him up there. If he won't be allowed to jump on you, don't encourage it while he's small.

Don't give him constant attention. If he is going to be alone during the day or night, He needs to start getting used to it now.

Never hit your puppy or yell at him. He doesn't mean to misbehave - he's just doing what's natural for him. You have to show him what's acceptable and what's not. When you catch him chewing the furniture, say NO or OFF firmly and hand him a toy. Praise him when he chews on the toy.

If you don't catch him in the act of misbehavior, never discipline him for it later. Dogs who appear to feel "guilty" when you come in and find a mess are actually only reacting to your anger. They may associate your anger with the chewed up sofa, but not with their responsibility for it!

Most of all, remember that the first few nights are the worst...it will get better!
