Very quick sketchy ref, not hugely accurate but shows a bit better how she's supposed to look.
Mainly dobermann body with a (realistically shaped) fox tail, colours and markings of a silver fox and blood spatters in the shape of the markings of a classic black and tan dobermann. Pointy cropped dobermann ears, though I suck at drawing those properly. Fur a between the short slick fur of a dobermann and the fluffiness of foxes.
Bright yellow eyes, I like to draw them with out pupils/glowing but everything's fine as long as they're yellow and not ale cutesy. :p
Collar optional, bandage around base of tail (like she almost got docked as well) also an idea but no drawn here. Hair colour can also be different as long as it's bright and flashy.
