How come they all look like bulls?
It’s the horns; both bulls and cows have them. In the photos below the cow is on the left and the bull is in the center. Do you notice the difference in the horns? A cow’s horns normally grow outward and curve up above her head, the tips pointing skyward. A bull’s horns normally curve outward and forward, along the sides his face, the tips not much higher than his head.
