They may have but that's a way to get a (maybe) tame wolf, not a domesticated dog.
It would take generations of breeding the tamest ones, with the behaviors you wanted, to get something like the beginnings of domesticated dogs.
I read somewhere, that it might not have been a process, but a unique event. Dogs are not just gradually tamed wolves, but domestication might have been started with a genetic defect that made them tame.
