Today's a bad day for me to throw together a dogpill-for-dummies post, I was thinking of writing a comprehensive summary one day of everything I know about the subject but that's a lot of work and I wouldn't plan on doing it for a long time.
You can find things on twitter related to the dogpill but it's honestly not a great place from what I've seen, or maybe I just haven't looked hard enough. Here's a few quick things I've pulled up quickly but it's honestly not all that great for convincing people who need hard evidence to be converted. There was one twitter post I saw a while back that had a clip of a girl being interviewed for a porn audition where she went off on how she thought girls with dogs was really hot, but only if girls were doing it. Here's some other stuff though.

This paper:

would've been the best place to start but unfortunately it's no longer publicly available.
In the mean time you can try this researcher's post:

combined with this:

I don't have the lie detector sources directly related to bestiality on hand, I'd have to dig further for it but it's a decent place to start. I'd also throw in this youtube video which I think it's pretty great to dogpill normies.
