In this episode, we break down the important elements of little puppy mental and emotional development.  Though formal training doesn't occur at these early weeks and months, beginning to develop and establish purpose and mental focus is super important.  When ignored at the early stages, problems develop later when more formal training is started.  It is very possible to not have separation anxiety, to not have dogs that get 'distracted' easily.  It all comes down to what you invest of yourself at these short but precious stages.
