Thankyou for your concern, however I'm very aware of all the controversy around these dogs. I too believe that somewhere down the line a Weimeraner or two was mixed in to create the color. This does not bother me. There is no such thing as a "purebred" dog. All the recognized breeds were created form the mixing of other breeds. Just because it was doneover a hundred years ago, and not 15-20 makes me no difference.
