FIRST OF ALL, KEEP AN EYE ON YOUR PUPPY.
The key to cost-efficient and worthwhile house training is supervision. As a responsible dog owner that wants the new puppy to be fully integrated into the home, you need to watch your dog constantly. You need to be knowledgeable enough about the breed to the extent that you could identify what are your dog's idiosyncrasies right before it eliminates. Does your dog sniff? Does he circle a certain “favorite” spot? Does he hold his ears in a certain position? The point here is to identify what the dog does before it makes an accident, then to work from there. In any case, watch carefully. This is the start of how to house train a dog.

ALWAYS PRAISE YOUR DOG IF IT DOES RIGHT.
When you think the dog is about to create an accident, move quickly! And by quickly here, we mean going to the dog before it does its business, and asking, "Do you have to go OUTSIDE?" Lead the way, making reassuring and encouraging noises all the way. When you reach outside, stay with him until the puppy successfully eliminates and praise him as he goes. "Good, go potty outside!" The trick to getting your puppy's psychology is to make him feel that he is the most important dog you have ever known.

CONFINE THE PUPPY WHEN YOU CAN'T WATCH HIM.
By keeping the dog limited to a small place, an airline kennel would be an example, you will train him to learn waiting to be let out. Your dog will soon think twice about dirtying his crate, since if he makes that mistake he will be forced to live with dirt and waste, which is something that a den animal cannot stand doing. When the dog is indeed allowed to go out of the crate, bring him straight to his assigned toilet area and compliment him for quick results. (At this point it will be very useful for you to read more about crate training, which is a must when you are learning how to house train a dog.) Tethering the dog temporarily is still another option to prevent your little one from hiding where they are out of your sight.

KEEP A REGULAR SCHEDULE.
Bring the dog out first thing in the morning, last thing at night, and many times in between. Give food and exercise on a consistent and frequent basis. Note that with regard to what you can do, what goes in regularly, will come out regularly. Be aware, when learning how to house train a dog, even of details such as how soon after eating does he need to go out. Something that may go against your house-training efforts is free-choice feeding. Is your dog also like most that will want to go out right after eating, after napping, and after exercising? It's important to know so that you can estimate the time when he needs to go and lead him to the appropriate spot the moment the dog demonstrates the signs of wanting to poo.
