Do you think you know about pigs and dogs? Take a minute or two and check out this quick and fun quiz. You might be surprised.

What was your score? I got a seven out of nine. Not too bad.

Did you know? Pigs are the smartest animals on the planet besides primates. They’re as smart as 3-year-old children, and pigs can suffer and feel pain just as we can. Think about it: If pigs said “woof”—would we treat them like we do? I won’t go into all the gory details about what happens to pigs on factory farms. And if you don’t want to know then don’t watch the video.

Just remember how smart pigs are and think of this next time you want to eat one!
