i was thinking about malnois at first -but he doesn't match at all- malnois have long slender faces with black muzzles and are usually larger/etc (a number of other things.) definitely not basenji in him eithor. And as far as Carolina Dogs go - that's what our doggie Whiskey is
(they're beautiful!) so i definitely know Norris is not a Carolina Dog. We are almost definite however now after several vets looked at him that he is a purebreed Jindo
So now we somewhat know!
thanks for your ideas!
