Genetic evidence from an ancient wolf bone discovered lying on the tundra in Siberia's Taimyr Peninsula reveals that wolves and dogs split from their common ancestor at least 27,000 years ago. "Although separation isn't the same as domestication, this opens up the possibility that domestication occurred much earlier than we thought before," said lead study author Pontus Skoglund, who studies ancient DNA at Harvard Medical School and the Broad Institute in Massachusetts. Previously, scientists had pegged the wolf-dog split at no earlier than 16,000 years ago.
"The concept of the alpha wolf as a "top dog" ruling a group of similar-aged compatriots," Mech writes in the 1999 paper, "is particularly misleading." Mech notes that earlier papers, such as M.W. Fox's "Socio-ecological implications of individual differences in wolf litters: a developmental and evolutionary perspective," published in Behaviour in 1971, examined the potential of individual cubs to become alphas, implying that the wolves would someday live in packs in which some would become alphas and others would be subordinate pack members. However, Mech explains, his studies of wild wolves have found that wolves live in families: two parents along with their younger cubs. Wolves do not have an innate sense of rank; they are not born leaders or born followers. The "alphas" are simply what we would call in any other social group "parents." The offspring follow the parents as naturally as they would in any other species. No one has "won" a role as leader of the pack; the parents may assert dominance over the offspring by virtue of being the parents.
While the captive wolf studies saw unrelated adults living together in captivity, related, rather than unrelated, wolves travel together in the wild. Younger wolves do not overthrow the "alpha" to become the leader of the pack; as wolf pups grow older, they are dispersed from their parents' packs, pair off with other dispersed wolves, have pups, and thus form packs of their owns.
However, the outmoded idea of the "alpha wolf" still has some legs in a real-world area: dog training.
Just as, more than six decades ago, Schenkel extrapolated his wolf studies and applied them to domestic dogs, so too have many carried the notion of the "alpha wolf" over to dog training. Certainly, just as parent wolves hold dominance over their cubs and human parents hold dominance over their children, owners hold dominance over their dogs. Until my pup gets himself a credit card and a pair of opposable thumbs (and stops dissolving into delighted wiggles every time I tell him what a good little man he is), I'm pretty much the boss in our relationship. But some trainers take the idea of pack rank to the extreme; dog owners are given a laundry list of rules of how to maintain alpha status in all aspects of their relationship: Don't let your dog walk through the door before you do. Don't let her win a game of tug. Don't let him eat before you do. Some (famous) trainers even encourage acts of physical dominance that can be dangerous for lay people to execute. Much of this is a legacy of those old wolf studies, suggesting that we're in constant competition with our dogs for that pack leader position.
But, you might ask, mightn't domestic dogs behave much like wolves in captivity? Despite being members of the same species, wolves (even human-reared wolves) are behaviorally distinct from domestic dogs, especially when it comes to human beings. Take the famous experiment in which human-socialized wolves and domestic dogs are both presented with a cage with food inside. The food is placed inside a cage in a way that makes it impossible for either wolf or dog to retrieve it. The wolves will inevitably keep working at the cage, trying to puzzle out a way to remove the food. The dogs, after a few seconds of struggle, will look to a human as if to say, "Hey, buddy, a little help here?" Even if the hierarchical ranks were some innate part of lupine psychology, dogs have behaviors all their own.
Most unruly behaviors in dogs occur not out of the desire to gain higher
rank, but simply because the undesirable behaviors have been rewarded.
Despite the fact that advances in behavior research have modified our understanding of social hierarchies in wolves, many animal trainers continue to base their training methods on outdated perceptions of dominance theory.
While we can get ideas of the types of behaviors to study in dogs based on what we know about wolves, the best model for understanding domestic dogs is domestic dogs. Dogs have diverged significantly from wolves in the last 15,000
years. Ancestral wolves evolved as hunters and now generally live in packs consisting most often of family members (Mech 2000). Pack members cooperate to hunt and to take care of offspring. In a given year, generally only the alpha male and alpha female mate, so that the resources of the entire pack can be focused on their one litter. Dogs, on the other hand, evolved as scavengers rather than hunters (Coppinger and Coppinger 2002). Those who were the least fearful, compared to their human-shy counterparts, were best able to survive off the trash and waste of humans and reproduce in this environment. Currently,
free-roaming dogs live in small groups rather than cohesive packs, and in some cases spend much of their time alone (MacDonald and Carr 1995). They do not generally cooperate to hunt or to raise their offspring, and virtually all males and females have the opportunity to mate (Boitani et al. 1995). Marked differences in social systems, such as those just described, inevitably lead to notable differences in social behavior.

So I pose this question: Is there really any need for Dog Experts? Don't we have enough DNA level experience by now and enough Common knowledge..lore if you like to suffice for managing this relationship?

My "prickly response" was based upon your implied notion that I was not an expert when you made this statement: "most true animal/dog experts agree that dogs, like many other mammals due indeed have and need friends." As I disagree, by default, I am not an "true expert." I take offense to that. I suspect that you cannot substantiate that statement with any verifiable science and as such, is your opinion.
I still maintain that if there is an established pack with more than one dog, and some humans nixed in, the pack members do NOT need any more "friends."
If I was too thinned skinned, then I apologize to you and my fellow members here.
We have diametrically opposed life experiences and opinions on parts of this subject. (In other areas we actually agree.)
I am not going to change your mind nor are you going to change mine, and that is perfectly O.K. Further debate on this subject is pointless.
Happy camping my fellow camper.
