Shotgun wedding.

Not much, at most it should a social misdemeanor like indecent exposure. I feel a puritanical streak here, people recoiling then finding a rationale. It's not like child abuse, if daycares or schools had the appalling environment that factory farm animals live in it wouldn't be tolerated. I see religious fanatics similarly condemn homosexuality, "it's unnatural stone them to death". People are just weird about sex. Including me, just the thought of sucking a dick skeeves me out but I don't think my prejudices should be the basis of law and morality.

Wow ...Holy Inquisition Some comments here could come straight from the Torquemadas... Perhaps the punishment could include quartering, swallowing molten lead ...

Sex with an animal deserves bizarre punsihments: e.g.castration etc, but murdering an animal just to please your gustatory senses is ok?
How does one castrate a woman?

They don't consent to such things. That's gross and horrible. People should be put in prison for that.

Hey, the only thing wrong with screwing sheep is that you have to run around to the other side to kiss them...sorry I couldnt resist

I would support the death penalty for any and all animal abuse.

I personally think its wrong to have sex with animals and discusting. Just me though. AS for the bible person saying animals that have sex with him goto hell, something for them to think about, the bible says basically only we humans have a soul. lol so animals don't go any where according the so called b.s. scriptures.

Who cares. As long as Old Shep is into it, I don’t know why anyone should get involved. I’m not into it myself but for some people, it’s the only closeness they have.

Somewhere in the Bible it has a comment about it's okay with one's handmaidens and goats. I always thought that was hilarious. Maybe that's where unicorns came from. LOL In reality, all animals have a sex drive. If you look around you'll occasionally see different species engaging in sex. Unfortunately, we are animals, not so far elevated above the other animals. That it occurs is no surprise, any more than sadomasochistic tendencies. I prefer women in an equal partnership but I also recognize that humanity is still very primitive.

Tell them it can be dangerous.

I think sex should be consensual between all parties. How can an animal give sexual consent? There is a woman on You Tube who brags about sex with her German Shepherd, and she shows her face in the video!

Tell them to go back to Montana.

They should take boudoir pictures of the two of them and post it all over social media along with details of the crime then 1000 hours community service at an animal shelter.

Obviously this question elevates humans behind their animal condition. It also introduces the idea of divine punishment by using the phrase "What ... should happen to people". But the question surprises me less that the responses.
Perhaps the venerable members should reflect upon the broader question of what the human primates do to other animals, including their fellow primates.
"Soliders are murderers" is a phrase that was coined by Kurt Tucholsky.
I would think that *beastiality** would rank much lower on my list of morally reprehensible acts human primates perform/commit on a regular basis.

That's sort of behavior gets my goat!

Castrate them

As long as the animal isn't hurt what's the harm? I met a man once who boasted he had sex with all of the types of animal on his father's farm. He said the chickens would die after sex and his father would give him a beating every time a chicken died. Bizarre, but true.

If this question seems a little odd, that’s because it is and I had a Bible thumper quote scriptures from the Bible to me the other day when the topic came up on a public transmit bus about a woman who did this and the first thing she said was thy ought to be put to death. Had to come here and ask non religious people to get an opinion on their views on this subject, of course.

Put them in a cage with a lion and tell em.... y'all have fun.

It depends if they're trying for a baby.
{edit} typo

The people in question should be castrated or chemically treated to remove their sex drive, as such acts against poor innocent and confused animals are beyond contempt and thoroughly nauseating.... the fact that there are human beings who actually engage in this activity are just further evidence as to why I prefer the company of animals over people

What should happen to a pooch fucking my leg ... without my consent?

The animals should probably be encouraged to interfere with the people, isn't that why beastiality is considered taboo.

Do what we normally do. Put the person on trial and punish them according to the law.

When I was in my 20's, my then boyfriend told me that during WW2 they had to put down a lot of sheep because servicemen were having sex with them and they got pregnant. They were afraid of what would come out. I came home and laughingly told my father the story I just heard. My father actually confirmed the story. Since my father was a scientist (Phd in Chemistry) I tend to believe him.

From what I have been told, this is fairly common in farming communities (I know several men who have been intimate with sheep/horses/etc). Not that this makes it right; personally I find it pretty disgusting. As for punishment, I think the registry some localities just passed to register animal abusers like sex abusers would be wonderful punishment along with either jail time or probation.
