Thanks for the info! I have been drooling over pictures of Spanky and Darla, they are gorgeous dogs!
So for these puppies for sale, one parent had to be pure biewer for the dogs to absolutely be carrying the gene right? So where does the chocolate come in? Was it a biewer bred to a chocolate? Since the chocolate gene is recessive, the parent would need to have both chocolate genes, and the other would have both beiwer. Should the babies not be colored one way or the other? I don't understand how they can be silver or black and tan, and yet be carriers of the biewer gene AND chocolate gene
