Someone please explain this to me. I must have it all wrong, but the gist I have gotten from dane sites is that if you breed a Harle (which I thought was black and white spotted, but is apparently merle?) to a black and white dog you will get what they call "merles" but appear to be double merles... I'm really confused. Please explain this to me. You cannot get a merle from two non-merle parents.. but that is what I have gotten the impression of. Simple terms for nolu's fried brain, please..
