My point to this first time puppy owner was simply that in order for a puppy to learn how to adjust to life with us, there are many things it must be taught outside of things that are addressed in formal dog training classes. As Carrie mentioned housebreaking, being calm around people, not barking at everyone and to that we can add learning its name, not to chew and destroy household objects, to understand basic words like no, good girl, sit, come. A four month old puppy is going to "learn" regardless, so we need to help her learn to live with us in a manner that will help her become a suitable companion, instead of one of the millions of dogs who are soon discarded because they are "too much trouble".
