For me, forget the alpha smalpha stuff..At this age, I am working on a good bond with my puppy
Basic stuff like sit/COME (most important), working on that puppy to get them to think "I" am the center of their universe
Patience, consistency, being fair, and not expecting a perfect puppy/dog.
I hand feed my puppies, figure out what motivates them, is it toys? food?
I kinda let them be puppies at this age, ignoring bad stuff, redirecting to good things, ALWAYS Praising, treating for GOOD behaviors even if you haven't asked for them.,
I think once you get a good bond going, everything else falls into place,,mutual respect
Thats just my quick view on it
