You will find many belief systems here. Some are rigid and all encompassing, with it's proponents having a need to discredit other belief systems in order to promote their own.
IMO, leadership (yep, dominance) principles are valid and an extremely usefull concept.
I've found many owners act like leaders one minute, and followers the next. This can be very confusing to a dog. It's natural for a dog to take instruction or correction from a leader, not from a follower. Pay attention to how you interact with your dog at all times, not just during the walk. Pack positions are fluid in order for a leader to be replaced if they become weak or unstable.
The idea that there is no pack leader in wild wolves is not a belief system, it's an observed fact of nature. Given that this is so, it would be quite impossible for dogs to have an "inherited" an instinct from wolves that wolves don't actually have. So to say that it's natural for dogs to take instructions from a leader, but not a follower, shows a complete lack of understanding of the true nature of the pack instinct.
I agree that what we perceive as pack "positions" are fluid; that's the nature of a self-organizing system. The structure changes with changes in the environment. And when you step back and ask why there would be up to 5 or 6 alphas during the hunt, and you'll see that none of them is leading the hunt; the prey animal is. So when the terrain changes, or the prey animal changes tactics, etc., each member of the pack will have a different approach to the hunt in response to these changes. That's why the "leadership" role seems to change hands. But the rest of the wolves are only "following" another pack member at any given moment because of his proximity to the prey animal, his speed in the open, his ability to shift gears in changing terrain, etc. He's not really leading though, and they're not following. The prey animal leads them all.
Here are some facts about wolves:
No wolf leads the pack (is always ahead of the rest of the group) when they travel together. Sometimes the parents are in front, sometimes the kids are. In fact the breeding female tends to take the lead more than the breeding male, who is what's traditionally thought of as the alpha male (a title which only connotes breeding potential, nothing else).
No wild wolf makes an issue over who goes through an opening (or doorway) ahead of other wolves. In fact, even the animals at Wolf Park don't engage in this silliness. You only see these types of behaviors in captive wolves, culled from various sources, who don't even know one another, and who engage in adversarial behaviors, the way they would with members of rival packs, not their own packmates.
The pack parents don't necessarily eat first after the hunt; quite often they let their young eat before they finally chow down.
No wild wolf ever does an alpha roll on a pack member. That's reserved for rival packs and/or lone wolves.
The concepts of dominance and submission are a complete fabrication. It's always the more "submissive" animal, for example, who wins the fight, not the most "dominant." The concept of dominance came from Konrad Lorenz, a Nazi biologisit who fervently believed in the social principles of Adolf Hitler and the Third Reich, including the need to "cleanse" the gene pool of undesirables like Jews, Poles, and Gypsies, and purify it with Aryan blood. Lorenz's political views seriously warped his theories on canine behavior. In fact, he never even studied wild wolves at all -- most of his observations were made on his own dogs, animals he often beat into submission for minor infractions -- yet the entire alpha theory rests squarely on his shoulders.
When you see "leadership" and "dominance" in canine behavior, you're viewing them through a specific lens. When you take a step back, you'll see that these are false concepts, humanized ideas that have no relevance to what's really going on in a dog's head.
