Canaan dogs are a reconstructed "breed". My vote is for the sighthounds as being true breeds for the longest time, as there is a plethora of primary source evidence for deliberate functional breeding - and these sources go back five or six thousand years.
Northern type dogs have been extant that long or longer, from pictoral evidence, but there is no evidence to support deliberate breeding, manipulation for functional purposes, or even deliberate domestication, for many thousand years following.
Until very recently, there were breeds maintained by the indigenous American peoples, dogs that demonstrated a marvelous range of functions and physical variety, that showed a real knack for breeding among the Americans. These breeds would have been up to 20,000 years old. Very few of these dogs have remained since European contact, sadly - some were simply exterminated in the rage to "purify" dog breeds in the 1800s, some passed away with their human counterparts, some were replaced or interbred with European strains.
