And in fact, what is being referred to as Dudley is not actually dudley (pink-no pigment). The yellow puppy who got the chocolate gene from both parents does have pigment (nose, eyelids, etc) , it's just not BLACK pigment, it's liver brown. The last poster is right, they're often pick of the litter, because in all other ways, they're a perfectly good speciman of a Labrador. And it's naturally occuring within the breed, unlike silvers. :)
