I have seen some stuff that is a little bit conflicting, or at least it leaves a question in my mind. Some things I've read say that a "Dudley" yellow lacks all pigment from its nose, and this produces a pink colored nose. I have seen other things say that if the yellow dog has a brown/chocolate colored nose instead of black, then it is a Dudley, which is undesireable. The reason I ask, is in about another year I intend to breed my yellow, Cami, to Chief my Chocolate stud, that is if she passes OFA and gets titled in that time. I don't think she carries a chocolate gene, but I was hoping for some clarification of the Dudley thing.
