11. Even cows can become aggressive animals.

When you think of cows, you probably just picture a bunch of them standing in a field. Cows usually stand, sit, and eat grass. If you work on a farm, you know they have to release this food quite often, too. Besides milking a dairy cow, you might not think much else of these farm animals. So, it may sound out of character, but cows can also become aggressive. An aggressive cow, bull, or steer can do a lot of damage pretty quickly, not surprising, though, with their big size and all (via Mental Floss). Not only can they damage property, but a charging bull can have fatal consequences.
If a cow happens to feel threatened, you may face some types of behavior similar to what a horse shows. An aggressive cow may lower their head and hunch the shoulders, flatten its ears, shake its head, have raised back hair, or turn to show his or her flank (via Benton). It’s obvious, but just in case, get out of the way as quickly as you can if you encounter an aggressive cow or bull. Even if it’s a stick, use anything large to ward off an attack and avoid turning your back on the fierce animal.
