I don't know anything about partis but he's cute. I didn't know they had that much white on them. Did you not ask about the AKC papers he supposedly had on him while you were there at the breeders? It's such a shame how there are SO many dishonest people nowadays. I would get him DNA tested. Even if you found out he wasn't full yorkie, you wouldn't love him any less. I think you need the proof to show to the breeder.
Did you get any paperwork on him? Micro chip papers? Anything with an address on it? I found out the hard way, when I didn't know anything about dogs. My Uni had papers but the "breeder" couldn't "find" them and would mail them to me. she was local, but when she finally got around to mailing the paperwork (surprised I even got them) for the microchip they were from out of state, a clear sign she is a broker or reseller.
