In more recent campaigns Justin has introduced porcs breed for specific purposes, such as law enforcement. I just noticed this wasn't included and wanted to bring it up to the community.
Porc selective breeding
I thought it was more of an idea rather than canon, I might be wrong though
The thing is that was more hearsay then hard cannon, if you want include it in the trivia at the bottom of the Porc page.
I know Jormr was meant to be bred for lumberjacking, and Jax was meant to be bred for the law, but I'm not sure if it's entirely canon given some of the other things we've seen Porcs believe about their pasts (looking specifically at McCoy when I say this, with his fake Grandpas and his mostly imagined internment at a farm).
