She looks very close to what my boy is very nearly a bi-color. She has a tinge of tan on sides of face, under neck & looks like a hint in the ears. Technically a true bi-color is all black on & around the face & head with just tan on legs with tar heals and usually black penciling on the front toes. Though most people will call her a bi-color, the same way most call my boy a bi-color.
Who the heck said sable? Not in any way shape or form. Pretty girl, I'm a bit biased though, love those bi-colors or nearly ones.
If the dam was solid black there is no carried sable. Sable is dominant in a GSD so it would be sable dog even with just 1 sable color gene. You can have a sable carry black, but not the other way around. Black is recessive so she would have 2 black color genes. Unless this is one of those Russian black showlines which is a whole other thing.
