10. Pig

Despite their reputation, pigs are thought to be the most intelligent domesticated animal on earth — perhaps even more than dogs. In fact, some studies have suggested that pigs are on par with 3-year-old children! The study in question? Pigs were taught to play simple video games with their snouts. They were able to distinguish between a scribble they had already seen and one that they hadn’t. Pigs possess an ability to focus that researchers don’t see in other animals, including chimps!

After watching the PBS show "Decoding Dogs", I would have to put dogs above primates and monkeys, but agree that all are intelligent. Sad when you think about the way most are treated in our world. If intelligence = power, I wonder how they all would treat us?
