The soul of the auroch is the first ghost that the dog encounters in the German forests after his exile in “Hundstage.” The auroch explains that she’s waiting in the forest for her life mate, the last of their kind, to die. She also tells the dog that she’s not one of the original aurochs that lived in German forests; the German scientist Herr Görlotz bred her and others in an attempt to recreate the extinct species. None of the new aurochs, however, can survive in the wild.
