My view is that if you can get a puppy to obey while it is under stress (measured according to the pups ability, not age, and progressing accordingly), you will end up with a stable and very obedient dog.
An excellent example is what you can see in Al Reanto's dogs.
As very significant by products, dogs trained in this fashion are also VERY self-confident, very focused and VERY agile and surefooted.
This "way" is directly opposed to the treats and rewards "way", because in the latter the dog works FOR HIMSELF, and in the former the dog works because of the bond between himself and the handler, and thus FOR THE HANDLER.
This "way" is not for sport dogs; at least not for sport programmes as they are currently configured, as you will not see the artificial "animation" that is so well liked in competition.
What you do see though, is a strong work ethic.
