Consistency and Patience. Never scold or punish your puppy for mistakes and accidents. The older your pup gets, the more he will be able to control his bladder and bowels. Eventually your pup will have enough control that he will be able to "hold it" for longer and longer periods of time. Let your puppy do this on his own time. When training is rushed, problems usually develop. Don't forget, most puppies are not completely house trained until they are 6 months old.
Once he seemingly has this idea down, move the string of bells to the left or the right of your dog and see if he moves to go and hit them with his nose; if he does click and treat! Next try moving the bells above his head and then closer to the floor. If he is chasing them with his nose in an attempt to ring them, then he understands what you want!
Potty training seems like a daunting task! It really does. I know people who avoid getting puppies just to skip this process, and in some ways I totally understand that! Puppies really are a LOT of work, and it is not just potty training! It can be varying aspects of housebreaking, teaching your puppy manners, making certain that it is well socialized, addressing early issues like persistent whining or separation anxiety before they become permanent problems, and tons of more areas to make sure that your puppy is on track to being a happy, healthy, well-behaved dog.
Lindsay says of this study, "Schilder and Van der Borg (2004) have published a report of disturbing findings regarding the short-term and long- term effects of shock used in the context of working dogs that is destined to become a source of significant controversy ... The absence of reduced drive or behavioral suppression with respect to critical activities associated with shock (e.g., bite work) makes one skeptical about the lasting adverse effects the authors claim to document. Although they offer no substantive evidence of trauma or harm to dogs, they provide loads of speculation, anecdotes, insinuations of gender and educational inadequacies, and derogatory comments regarding the motivation and competence of IPO trainers in its place." 
On the other hand, praising a puppy for doing the right thing works best for everything you will do in your life together. Make her think that she is a little canine Einstein every time she performs this simple, natural act. Be effusive in your praise—cheer, clap, throw cookies. Let her know that no other accomplishment, ever—not going to the moon, not splitting the atom, not inventing coffee—has been as important as this pee.
