That is a fine bred dog Art/King Fish. Carries as much of the Mayfield Nigger dog's breeding you are going to find today. He looks like his breeding and has the right color. Goes heavy back to Tudor's Dibo etc. in the 14th generation.

My Mule dog (Jackson's Mule) was a clone looking replica of the Mayfield's Nigger dog. Mule was black and white markings. cheers
