I have a new, smaller sounder that showed up on my ranch today, and I have a concern: in the mix is a young sow, black, who has stiff hair sticking up on her back like a mohawk. I've seen pictures of pigs like this, but the sows on my place are usually multi-colored, and fairly smooth. Is this an indication of more of the "Russian" type, as opposed to a domesticated one, and if so, would she be more aggressive? Or are they all pretty much the same wild/domesticate blends in the U.S., with differing coat types? Here's the video:
