Works by Mech? Who? Lol... Google is wonderful. I will take the info from the Minnesotans for Sustainability website and cherish it.
What goes on in an actual wolf pack and the way THEY interact with each other is alot different since I am going to go out on a limb and say it is a little easier for a dog to communicate with another dog than it is for you or I to communicate with a dog. For a human to observe wolves in the wild and count corrections dished out and put it into a table is hilarious.
I don't need to read works by anyone to prove what I am saying is accurate, I've read enough, and most of my knowledge is from word of mouth and what I've been told and shown by extremely intelligent and experienced people. One of the reasons that it is so important that a dog know how to properly walk, and knows his role ON a walk is because the same people who let their dogs walk in front of them, and/or pull them, are the people who feed them table food for no reason, let them sleep on the bed/couch, leave food in their bowls all day long, let them enter and leave buildings before them, and etc etc etc. Those people are also the same people that during the life of their dog if they happen to get bitten, it is the dogs fault. It has nothing to do with the fact that they worried about the dogs happiness instead of giving it structure and balance from the moment it was born. The dog didn't bite you, it corrected you. It was right when it corrected you as well, because in it's mind, it owns you. The moral of the story is, there is no structure to the dogs life. It has developed its own structure and in it, it doesn't take orders from you.
As far as the statement about happiness and how they are walked that you are requiring a google search with a link to back up. I'll pass on finding a meaningless link. Just like we are born to listen to our parents, dogs are born with certain inherent behaviors. Natural bodily functions, the desire to explore, sexual desires, are some. Most important to a dog owner is the fact that dogs are born to follow. No one said it had to be "rigid" or "force-based". I didn't tell you that if your dog doesn't walk next to you that you should beat it. When wolves migrate, the alpha is out in front almost all of the time unless it lets a subordinate take the place, which almost never happens especially while hunting. Do you think ALL FOUR of your dogs would be happier owning you rather than living a laid back life where they chill in the house, with no responsibilities/burdens of guarding/gathering and all they really have to worry about is to do what they are told, and just can't wait until their alpha decides to go for a walk because they'd love to go along with them?
To reiterate, I never said you have to "DOMINATE" and "CONTROL" your dog. What you may view as those two things are simple little rules that 95% of Americans who own dogs consider being "mean", where in actuality you'd just be establishing guidelines that you dogs would have to follow if they were wild and in a pack.
