I've never been a big fan of the view that domestic dog behavior and training issues can be seen in terms of (human interpretations of) wild wolf behavior, i.e. as some sort of "dominance vs. submission" continuum. This view is central to the "master trainer" approach (i.e. training by punishing undesireable behavior as opposed to rewarding desired behavior), but a lot of positive dog trainers place much stock in it as well. Nonetheless, I've never been really comfortable with the idea that to teach a dog to live in harmony with humans we need to try to act like wolves. First of all, dogs aren't wolves, and furthermore, even if they were, our understanding of wolf "dominance" behaviors is quite likely flawed.
Anyway, via The Austin Dog Trainer--Positive Dog Training Blog, I found a short article called Some Thoughts on Letting go of the Dominance Paradigm in Training Dogs. There isn't any "about the author" info listed, but I gather from the article that she is a "wolf educator" and may have some connection to Wolf Park, a nonprofit wolf education and research facility in Indiana.
At any rate, if anyone has interesting links they would like to share on this topic, please leave them in the comments.
