Creating An Individualized Training System

I have been carefully observing the different dog owners at the park and the way they use commands and gestures to train their dogs. I am hoping to incorporate some of what I have learned into my own Rottweiler training system for the puppy.
Some of the trainers I have watched in videos seem absolutely mean like drill sergeants or something.
This puppy is a member of the family, just as if we had brought home a baby instead of a puppy. I expect that it will take a lot of attention, time and effort in order to mold it into a well disciplined member of the family.
I have found a recipe for some great new treats that will be awesome little training rewards as we start working with the puppy. Of course, I have to find a way to keep it fun and entertaining for both of us or we won't ever follow through on the training regimen.
