HE IS BEAUTIFUL! If I ever find one like him that is attainable to me, I'll bring them home in a heartbeat, I have wanted a blue merle forever. Stunning little boy, congrats on your new addition!
The merle debate is about genetics and health issues to my knowledge. I haven't looked REALLY deeply into it, but something about if you breed two Chis that carry the merle gene you can have puppies with health/immune problems. My understanding is if you breed a Chi that carries the merle gene with one who does NOT, than you should be fine. Someone correct me on this?
