Is there a distance pigs must be by law from a neighbors residence?

My father has a neighbor that owns a very small lot of land in his backyard. And he’s being rather irritating about his small lot, and tries to make his property look bad by doing various things to that small lot he owns.

Recently, he put a pig inside the lot. Every time he approaches him when he’s on the lot, he accuses my dad of harassing him and calls the sheriff over.

So, what kind of codes exist that would force him to remove this pig from the small lot, if any?

He lives in Wood county in Ohio. I’m not turning up anything through searches, and am unsure of any site to look up health codes. Please help me out here.

Thanks!
