A friend of mine has a beautiful Dalmatian. Friendly, energetic and lovable, she was a perfect family pet… but she wasn’t the smartest pooch on the planet. See, she knew how to go through the pet door out into the garden, but she had no clue how to get back inside. It never occurred to her that the flap could swing both ways. So she would sit outside and howl until my friend would open the door.

Repeated demonstrations of the dual movement of the flap had no effect; it just did not compute. The dog breeds on this list, however, probably don’t have that problem. They’re widely considered to be among the cleverest canines in the world. Take a look and see if you agree.

1. German Shepherd

No surprise here. German Shepherds are the world’s best police dogs, military dogs, and some have even been movie stars (remember Rin Tin Tin?). Brave, loyal, smart and strong, they’re the total package.
