GranataPet brand dog food figured out a clever way to beat the problem with food ads: In most forms of media, consumers generally can’t taste or smell the food being advertised. Granted, they solved the issue with dog food, rather than people food, and the billboard is in Germany instead of everywhere, but they solved the issue nonetheless. When one checks in at the billboard via Foursquare, some of the dog food slides out of a dispenser and into a bowl, ready for dogs sample. The billboard isn’t too complicated, as the checkins are sent to a server that is connected to a box which controls the dispenser. Head on past the break to see a video of the billboard and adorable freeloading dogs in action.
