She's black, right? Well, not so fast. She actually has tan points! They're muddy and a bit hard to see, but they're definitely there. Genetically, this dog is basically the same as the Xolo that I talked about before. I'll repeat myself:
As I said, this dog is tan pointed. This is most obvious on the lower legs and the little tan "pips" above the eyes. The amount of tan on dogs with tan points can vary greatly, and the markings on this dog remind me a bit of a Labrador retriever mismark I once saw. It is very possible that this dog also carries recessive black, which is the form of black seen in the German shepherd breed. I am going to assume she does, which means she is ata tan point carrying recessive black.
As with nearly every other German shepherd out there, this dog has a mask (very very rarely you will see a GSD without a mask). Masking will either eliminate or nearly cover the tan on the face of a dog with tan points. Since the masking gene is so prevalent in the breed, it's almost guaranteed that this dog is EmEm masked.
I do wonder about the possibility that this dog could have a copy of the brindle gene. The gene was once present in the breed, though it was though to have died out. Though there is a small possibility that it is carried by the recessive black dogs, I really doubt that this dog would have a copy of the gene. Unless she's actually part Dutch shepherd, that is! However, this dog is listed as a purebred German shepherd and as such I will treat her as one. That means she must be kk non-black or brindle.
This dog does have a little white on her chest, but there are very few German shepherds out there (the "Panda shepherds") that have any white spotting genes other than solid. As such, this dog must be SS solid with residual white.
So, that is ata EmEm kk SS or masked black and tan with residual white.
