And I am agreeing with the other posters too! Puppy time is about play. Play walking on different surfaces, play going through a tunnel made from a sturdy box or under a chair, play romping up and down a step or two. I did put my Cubby on the counter and taught sit, down, paws up, touch, and shake -- that took all of 10 minutes because shelties are eager and smart. We learned stay or wait for picture taking! The rest was play.
The only kind of useful training is leash training in the house or a small area of yard. Let the dog walk you around while you are holding the leash just to get used to that. After that is fine with the pup, start calling the pup to come along to you on leash using a treat. Then progress to walking where you want to go using a treat. As the pup gets older you can stop every time the dog tries to get ahead of you and pull. If you practice this in a boring hallway or like me on my deck, the pup learns early on not to pull.
Carrying through places, even a 5 minute walk outside being carried, exposes the pup to the sights, sounds, and smells of the world. It helps the pup start making sense of life and not fearing it. It is the very best thing you can do. Your holding and cuddling makes the dog feel safe as it views the world. There is plenty of time after shots to explore the world, at first, just watching is enough.
Training, real training, can happen when the puppy's mind is more mature and in some instances (like agility) the body too. We did obedience 1 & 2 and then scent 1 & 2 at our dog school because mentally and physically these were appropriate for his age. Now that he is over a year, we can take obedience 3 which has more jumping practice and a much faster mental pace. Also, in another month or two there is agility when I know his joints are all mature.
Raising the pup is a process of exposure and expanding the world -- just like raising a child, same thing. Enjoy each step and don't rush anything. It's fun just taking time and really having some quality bonding.
And . . . with California, Central California, we have a major, beyond major, parvo problem. Many people I know have lost one to parvo. It is important to take it really seriously and just protect the little ones until shots are complete.
