I don’t think many people would base their behaviour off wolves, parrots, gudgeons, mollusks or whatnot. That’s such a random species to choose.
If anything, I would conjecture that the causality is actually in reverse: the ideas of pecking orders and dominance hierarchies were well-established in the scientific communities among zoologists and social psychologists (and even in common parlance), so people who studied wolves didn’t question external validity of their studies on captive wolves.
The wolf is not a random animal. It's a big predator associated in popular culture with aggression and dominance, e.g "a wolf in sheep's clothes", "the wolf of wall street", etc.
