Professor David Macdonald, a leading ethologist, was not best pleased that the wolf documentary films he was involved presented wolves as having organised, co-operative, closely planned hunts. However he has no problem with discussing dominance in various species he has studied.
His view was that it could just be luck and chance that the prey would turn from a wolf on one side, inadvertently then turning into a wolf on the other side.
Or that if one wolf caught hold of a large prey item thereby slowing it down that just made it easier for the others to then pile in, which just happened to reduce the risk for the catcher by further immobilising it, with everyone looking to catch the prey for their own benefits.
I.e.may well have been chance, opportunism, common purpose and luck, not a carefully planned strategy, although presumably learned experience occurred over time
In the same way I have certainly seen dogs "pack hunt" in the same way, with one dog turning the prey, deliberately or accidentally, into another dog on the other side, with it being logical for the dogs to be running either side of the prey as that gives each best access, without their line of sight or angle of attack being obstructed by another dog.
I have also seen park dog fights where it has been two onto one a couple of dogs have attacked another dog by going one to the rear left and one to the front right i.e. opposite diagonals, so the victim cannot defend itself on both sides at once and the attackers alternating their attacks, depending which side was vulnerable at that point.
Back in the early 60s Scott and Fuller described Fox terrier puppies in their study having to be housed in no more than threes as otherwise one puppy would be held at the front and rear by two puppies while a third attacked its middle.
To me this seems pretty similar to the organisation, or lack of organisation, of hunting wolves so I do not entirely subscribe to domestic dogs not having apparently organised pack hunting behaviour.
"Pack" after all is merely a term to describe a more or less affiliated canine group of more than one dog.
I do not agree with a linear hierarchy but there are certainly control (i.e. "dominance"), issues and agenda conflicts between dogs, and between dogs and people, including the poeple they cohabit with.
However these situations are dynamic, based on learning and experience, and the balance of a number of variables at any one time although the more frequently a certain outcome is repeated, the more expectation is set up of that outcome being stablely repeated in future, i.e. a hierarchical structure/expectation begins to emerge.
There are suggestions that it is a submissive hierarchy, not a dominance one but for that to work there has to be someone who less submissive, i.e. more dominant, who is submitted or deferred to.
However I have also on several occasions seen dogs very definitely, deliberately and forceful pin other dogs to the ground (who very clearly were not voluntarily submitting), muzzle pin or paw smack them, all things I have heard it said never happen when arguments against there being such a thing as dominance are put forward.
IMO too much in dogs these days is about fitting behaviour into certain political agendas (as with child rearing), and owe too little to accurate and unbiased observations of very widespread canine interactions, in a wide variety of populations and circumstances. Our interpretation of dog behaviour may change, dog behaviour itself changes very little over time.
