i think there are two piebalds in the US that have breed granted full registration and recognition of their colour for the purposes of showing recently through the American Kennel Club, here in Australia they are still unable to be shown and can only beon limited register, and are pets only, although very uncommon ones. There is a facebook page run by the owners of my dogs sire called Gammonwood Pied Mastiffs, which has a lot of photos and information on the Piebalds...plus photos of my sweet girl so I am heavily biased!
