Dogs were domesticated at least 15000 years ago. Artificial selection can work a lot faster than natural selection, particularly since mutations deleterious in the wild are allowed to persist in domestic species.
Most breeds diverged only a few hundred years ago. Original domestication date is irrelevant.
