While I am quite familiar with what the merle genes are, what causes them, and what breed gets them, I am a little bit weirded out that rough and smooth collies do not get the red merle. In The Complete Encyclopedia of Dogs, Esther Verhoef-Verhallen wrote the book to FCI standards and says that sable merle includes a wide range of colours including red. Argh! So confused!
