Wolves became domesticated when men would toss them pieces of cooked meat from the fire.
Before that, there was no synergy, no compatriotship.
The relationship came first because of the smell and taste of cooked meat.
With all due respect, your theory attributes more adaptability to wolves than they are capable of...even now.
It was cooked meat that transformed wolves into dogs.
More like, those wolves who could amiably be around humans got fed, and thus had a higher survival rate, while those wolves which acted in a hostile manner towards humans had a much lower survival rate.
