One theory is that as wolves followed early hunters throughout their claimed homeland of the harsh Siberian Steppes, they would feed on discarded bones. The wolves would safely track humans from afar. Generation after generation they grew
closer. Symbosis probably occured at this point where both were comfortable near eachother. Whenever a potential threat to both occured the wolves would probably bark or make noise. The theory of early dog domestication iirc states that around or before this point the most "tame" or human-friendly wolves grew gradually attached to said humans, and forked off their genes.
A similar breeding story corroborating the theory is pic & video related. This is how the Russian military successfully cross-bred the Volkosoby wolf-dog.
