I don't know very many things, but I do know hog poop when I see it. Mainly because a buddy and I came across a patch of woods, about an acre, that had several intersecting hog trails. Man, there must have been a thousand hog turds in there!

Also, I've seen "hog poop" that had "hog hair" in it. We can dump a carcass at our "gut dump" and come back later and not be able to find a scrap. Between the buzzards, yotes, and hogs, not much is left behind.
