I have heard a lot of things about border collies with mostly white faces. I am aware that in some cases a MerlexMerle crossing can result in blindness and deafness in mostly white offspring. But my border collie is from two traditional black and white border collie parents. She sees and hears just fine. So my question is, what causes it? Is it normal for her to have a white face and untraditional markings?
Thanks so much:)
