Sort of depends on what your long term goals are with the pup. Do you have any plans of getting involved in formal training or any sort of dog sport?
When we raise pups it's with SchH in mind, so with young pups we do a lot of imprinting for obedience (focus, sit, down, heel, recall), lots of rag and ball play of course, start tracking, etc...
But that's really mostly imprinting, not formal training. Just teaching them to love to learn and that working with us is fun and to build a foundation for later. I also really like to get them out to childrens' playgrounds and over different types of agility equipment to help build confidence and coordination and have fun. Most of their days are pretty much just being puppies though. Lots of socializing, playing with us and the other dogs, building good habits in the house, etc...
