How can I housebreak my new puppy?

Teach him specific commands that expect him to do his business as told (like "wheewhee" for no.1 and "poopoo" for no.2). Say it everytime he does his business so he learns to ociate the word with the action. Then, find a designated place where you want him to do his business (on a newspaper, a certain spot in your backyard, etc.) and bring him there everytime he starts doing his business. Don't forget to tell him the commands while he's doing it and praise him when he's done. The pup should learn it within a few weeks at most.
