The only aspect of "artificial" selection in dogs that's really artificial is the fact that theoretically any breed of canis familiaris can produce viable offspring with any other. We've artficially suppressed speciation.

But how long would it take a population of chihuahuas and a population of great danes to fully speciate in wild conditions?

That's an instance of mechanical isolation. They certainly can't mate and could be considered as true species.
