I order that the previous commentator be hanged for being crass. Dick.Napoleon complex, anyone?

I've always understood the difference between hanged & hung when it comes to people vs. inanimate objects, but what is the rule when talking about an animal that died by hanging? I always thought the rule was "hanged" for people, and "hung" for animals, but I feel like I may have been in error all these years.

Anyone have an answer?

Thanks!
