I think that's all a bit much. Dogs need structure, but not necessarily that kind of "discipline". Some of the citations are more about "dog mythology" than "dog psychology" (for instance, all that old-fashioned "dominance" stuff). Some of this advice is probably going to get some people and their dogs in trouble.
The think to remember is that every dog is an individual, and trying to work things from "tip sheets" can be troublesome. There are lots of good books out there with great advice about how to go about training effectively. One of my favorites is "The Power of Positive Dog Training" by Pat Miller.
