Hi there, I read a book ( I cannot remember the book, or I would gladly post it) involving training and behavior. It mentioned a program the US Army started called the "Bio-Sensor Program" and then became the "Super Dog" program. They introduced puppies, at an early age, to various stimuli to prepare them for "the unknown" as MWDs. I remembered a few of the techniques and implemented them to mine, but I have a real problem with introducing them to new people because I don't know anyone in my own country other than my family (who don't really care for dogs much) lol.. I don't have a link either, but I suggest Googling it. It is definitely worth looking into.
