When i got my dog, I just put newspaper down. They're going to pick a spot to go on their own anyway, so they'll probably not use the newspaper the first few times. Once they pick their spot, put the paper there. When she used the paper I gave the usual praise. Then I just moved the paper closer to the door, and eventually outside. Once she went outside, it was over. Correct them on any accidents they have inthe house and praise when they go outside. A dog in the wild wouldn't crap near where it sleeps, so you just gotta show them outside is the place to go. It took like 2 weeks. Also frequent walks will help, cause chances are the dog wil get the urge to go and you can praise him for it.
Don't yell, don't get mad and hit the dog - Especially on the nose! Imagine someone coming by and kicking you in the nuts. Even if you just "lightly tap" them in the nose, flick your nuts and tell me how it feels. Yes, I have hit my dog for things like chewing holes in walls and such, but never on or about the head and face. If you're going to hit them do it on their butt, and it's probably better to use a rolled up newspaper or something that will make alot of noise, that's what really gets their attention. I haven't had to strike my dog in years, and if she is ever misbehaved enough a paper cracked on a nearby table or chair will do the trick.
