In the rat race of body piercing even our pets are not left behind. The reason behind animal piercing is painful.
We have seen many bulls around with pierced nose. However, they do not have that as a result of fashion statement, rather they have to suffer this piercing because of their master The reason behind the piercing is the self protection of man. Like, bulls are powerful and dangerous animals, which if uncontrolled, can kill or severely injure their handlers. However, the nasal area of a bull is sensitive, so the nose ring enables the handler to control this powerful and belligerent animal with minimal risk of injury or disruption by exerting stress on one of the most sensitive parts of the animal.
Poor bulls cannot even speak to anyone about their pain.
