Puppy training does not have to be hard or frustrating. Puppy training is the responsibility that you signed on for when you brought the little fella through your front door for the first time. Some people believe that young puppies, those less than 16 weeks of age, should not be exposed to any sort of a puppy training program. Their thoughts often revolve around the conception that puppy training will have a harmful effect on the socialization process especially when discipline is used to define what acceptable behavior is and what is not.
