Great article Nelson. I could watch your dogs work all day long!
You had referenced a video of that first session you did with the pup - did you find it, and if so, could you put it here? I know a lot of us (myself definitely included) learn a lot better by seeing something done. Even though my dog has a pretty decent "drop it" I still know it could be improved and maybe trying this would help. As it is, she'll slowly drop something out of her mouth, chewing as she goes. For a pet dog, this really isn't critical, but I would still like an immediate dropping or outing of the object. God forbid she ever pick up something dangerous.
