No one here seems to have any idea what they are talking about about. 1. You put a ring in the pig nose so it doesn't root and eat the truffles, 2. Dogs have a better sense of smells than pigs by a lot, 3. Big brains don't come from standing upright, whales and dolphins have larger brains, 3. Brain size is important for intelligence, almost always the larger brain the more intelligent, the whole nonsense of body to brain ratio be more important was to make half the human population not feel as bad about having smaller brains. Almost always, more brain == more smart.
