Is your dog smarter than other dogs?

"Aren't you just the smartest little guy in the whole entire world?"

Be honest: You've probably said this to your dog before. Maybe it's because he once successfully fetched a tennis ball that was hidden by some bushes. Or how about that time he barked in the direction of your apartment keys while you were looking for them? Or perhaps it's how he can make toaster waffles for you in the morning. (OK, that last one is actually really smart.)
