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.
A training class is not there to train your dog. Its purpose is to teach you to train your dog so you will need to be committed to train your dog for short sessions (5 minutes) several times a day rather than just simply turn up for classes! This little bit of training everyday will be repaid with a lifetime of living with a well behaved dog. You will also learn to avoid problems before they begin as well as receive help to overcome any that you already have with your dog.
