Hmm could that be a collie mixed with a red merle BC? The anatomy can be quite similar and it could be hard to tell a mix. Unless it's some odd double dilute sable merle and white or something. I've never seen one with that coloring and I know when I was involved in showing my collie and studying color genetics etc, red merle was not in the genetics charts.

I was looking at some red merle BCs. Just wondering if that collie could have some BC in her. Odd
