Is that a rottie? Love when their ears aren't clipped C:
Haha, I might just be tired and confused, but I don't think Rotties ears are clipped, ever? Their tails are traditionally docked, as this Rottie's tail seems to be. Are you thinking of Doberman Pinschers? Those come in black/rust as well and are traditionally docked and cropped. Or you might be thinking of some bully or molosser breeds that are sometimes cropped?
