Well, GentleLake, we do want our dogs registered ABCA, and the ABCA does ask what color your dog is. Since we're intending to sell some of our dogs, it kind of makes sense to know if a dog is a merle or a tri merle. That does not make us candy color breeders, and just because some of our dogs are merles does not make them any less able as herding or working dogs. In fact, so far the few we have had have all displayed spectacular herding ability and instincts. I don't even know where you're getting that impression from that we breed for color (and yes, I am able to read forum disclaimers, thanks). My OQ was simply if the dark brown has anything to do with tri or not, to understand the genetics, and I understand from the info provided that it is a different thing.
Thank you for those who provided useful information, my question has definitely been answered. The pup is a blue merle, not tri.
