y'all ain't been around cattle. you put one of those rings in the bull's nose. then you add links to the chain depending on how nice it is. if it's real nice, it doesn't need extra rings. if it's a mean old bull what'll charge you as soon as it sees you, that 30 foot chain'll slow it down a titch, and maybe if'n you're lucky you can sneak up and hook it to a post so it can't get you.

a woman with a septum piercing is kind. les'n she got herself a 30 foot chain attached to it
