Feral ones can be holy terrors. But the ones you see now on people's places, are as docile as any Herford. Not all of them have the magnificent spread like the white cow in the pic
@Brute 23 posted. There are lines that are noted for tie huge horns, and show and ornamental LHs are bred to have those horns. But a vast majority of them, the "using" LHs, have horns more like the red one, third from the front, standing to the white cow's rear. You'd be surprised at how they can maneuver those horns through working pens, chutes, head gates etc.
