I'll be honest -- I wouldn't have figured out that.
Clever Boy: Dog Figures Out How To Pick Up Four Tires At Once

Because this dog wants to make it quite clear who’s a good boy, this is a video of a German Shepherd looking dog figuring out how to stack and pick up four tires in a single bite. Impressive! I could almost see the gears turning in his head as he figured it out. For reference, I can’t even pick up a single tire with multiple bites, but I can fit an entire pack of Sour Patch Kids AND Reese’s Pieces in my mouth at once. See? “Maybe take them out of the plastic next time?” I’m saving them for a movie later.
