again, back to horses.....but I have seen friesians (pure black dominant gene) mated to other Black horses throw palamino babies (golden body, cream hair)....hec, I even saw a chesnut friesian, which is said to be impossible genetically....dont ever discount mother nature...she always has the neatest tricks up her sleeve. In horses chesnuts are the most recessive of the colors...but all I ever see in my program here are chesnuts. neither of our stallions are chesnuts....not too many of our mares are chesnuts...they must be coming from somewhere....

and its very possible the same happened with WGSDs...not saying it did....its just possible....you can typically figure out the parents genetics by the time they've had their second get....so it wouldn't be too hard to breed colored dogs to whelp whites even if it was just two or three a litter...not hard at all. Thus your genetic base starts to expand as far as the whites go.
