This way of crate training is also ideal if you live in an apartment and do not want to upset your neighbours with them having to listen to a screaming unhappy pup.
When planning to get your puppy also plan on being with it 24/7 both indoors and outdoor for at least a week. Making sure you have all the shopping in that you will need if you wont have someone to shop for you. The longest you should plan on leaving it alone for the first few days is to take some rubbish to the dustbin. Also if you can, when arranging to collect the pup for the first time, try for as early in the morning as possible so as to give you a full day with it before bedtime.
It goes without saying that the crate needs a cosy blanket or bed. At the back of the crate in one of the far corners put a bowl of water on one side and on the other far corner is where you can put it's feeding bowl. This is to make sure that the dog is forced to go in and out of the crate and also sees it as somewhere good and comfortable to be. You can also occasionally throw one of his/her toys in the crate so the pup has to go in and get it. At this point don't attempt to shut the door at all.
Just as you are about to go to bed, take the crate into your bedroom. Place pee pad/s close to the crate and leave the water bowl at the back of the crate. Do not shut the door. Take some of the pups toys in the bedroom and put one in the crate and leave the others on the floor of the bedroom. Make sure that elsewhere in the room there is nothing comfortable for the pup to lay on and sleep. Be it a pillow or whatever. You need to make sure that the only comfortable place to sleep is in the crate. Last thing before you get into bed is put the puppy in the crate using the words you intend to use for the rest of it's life, such as "In your bed" - "Go lay down" - or whatever. Ignore him when he gets out.
If your puppy hasn't come to you pee pad trained there is a chance you may have to clean up a couple of wee spots, but you should have made your pup do it's last wee before bed anyway, so there shouldn't be much, if any.
This first night your pup will whine a bit to get up on your bed, wander around aimlessly, play with it's toys and occasionally doze off either on the floor or the crate. Do try to ignore it. What you hopefully wont get is the screaming and howling that you would get if you had locked it in it's crate from the beginning.
Continue this routine both day and night and at no point shutting the door, and about the 3rd or 4th night you should see puppy sleeping all night in the crate. The night after pup first sleeps happily all night in the crate you can attempt to put him in the crate as you get into bed and then shut the door for the first time. Make sure you don't speak to him apart from giving him the sleep or bed command words. If he want's to get out during the night, get him out and take him to his day time pee area and give the weeing command that you use. Once he has peed then put him back in his crate, closing the door again. No talking to him.
Once pup has managed to sleep all night with the door shut on him shutting him in his crate during the day should be able to happen automatically.
To test this out. Take him to wee and then directly put him in his crate with his bed or crate command, shut the door and then leave the house. No talking to him/her. Pup will be listening for you to walk away from the door so make sure you do walk a decent distance away. Count to about 20 then slowly walk back in, silently walk to the crate and open the door, saying nothing. Just treat it as all matter of fact.
Leave it a fair few hours before you try this again, but each time you try it, leave the time you are gone for longer.
I would say that by the 5th day you should have a puppy being able to stay about 10 minutes crated during the day, and sleeping all night crated as good as gold.
It's then up to you how fast or slow you take the crating process for the day time.
Regarding leaving water in the crate at all times. I personally think it is cruel not to. Just for the sake of the fact that a dog may wake us up for a middle of the night pee I find it wicked to leave it thirsty. I myself drink at least a half pint of water during the night and wouldn't be able to sleep without it so why would I expect a dog to do so?.
