Prove that dogs are smarter? Dogs only have social "intelligence" (which isn't even intelligence). Dogs aren't smart, all the dogs I've seen (and I've seen a lot) were dumb, aggressive and pure evil. I'm not ignorant about dogs, I just hate them because they're bad pets. And they probably aren't smarter than pigs, violence isn't an indication of dumbness, humans are violent and more territorial than pigs but still smart. Humans also seem to have a pecking order, constantly fighting for power and wealth (at least the greedy and power hungry ones do), dogs are only good for hunting/guarding and as livestock (they were used as livestock by ancient Mesoamericans, Asians, Celts etc. For hundreds/thousands of years.
