How to teach my puppy not to pee and pooh in the house?

Your going to have to take him out more often, for a new puppy every 2 hours is to long for them to hold it. Also watching him and his behavior, if he begins to sniff around take him straight outside. I'm not sure on the exact story behind this but my family is famous for house training their dogs by hanging a small bell from the door knob of the door they took the dogs outside from. Everytime they took the pup to the door they would take the dogs paw and hit the bell, sooner or later the dogs learned to hit the bell to go outside instead of barking. I've done it for every dog I've ever had, its just a neat way for the dog to let you know that it has to go outside (I'm currently working on them hitting a doorbell to come inside, so far so good). It does however take a couple weeks of constant taking them outside every hour for them not to have accidents inside the house. Taking your pup outside more often is definitely the answer.
