Geez Jerry.......it was just a joke about the pedrantry of this place! I truthfully have read about dogs being developed as an aid to herding sometime around the 8th or 9th century, but I don't recall the source....it was a long time ago.First, what we know as "purebreds" are a newer phenomenon going back only a few centuries although many of the "purebreeds" go back further. It's on;y been in the past few hundred years that we have begun to "catalog" these and develop newer breeds. The oldest known breed I believe, outside of possibly the Dingo, is the Pharoah Hound whose ancestry does date back to the time of Christ. Outside of that, I haven't got a clue!
Good luck, but I wish I hadn't mentioned it......
