Your new puppy is going to need a lot of instruction from you at first in order to learn the rules of the household. Training your puppy the right way, the first time, will ensure that your puppy grows up into a well behaved dog. In addition, a puppy that learns that rules of the household is a happy puppy; the puppy knows that he or she is doing a good job, and the puppy adores the positive feedback from you.
Puppies are delightful little bundles of joy, though they can also be almost uncontrollable little bundles of energy. Your new puppy is going to be testing boundaries at every turn, and your interactions with your new puppy will help your puppy to quickly learn appropriate and acceptable behavior.
