Check in: snack out - billboards that dispense dog food with 4square checkin

Here's a nifty little poster that aims to train dog owners into considering GranataPet dog food for their four legged friends. It's a classic sampling tactic, upgraded with GPS and 4square. Billboards were fitted with a black box full of food and the message one could check in to snack on it, which the owners did much to the delight of the snackhungry dogs. Soon the dogs were dragging owners toward the billboard for a mid-walk snack.

Via Adfreak who also point out that dog food scented posters have been all the rage for a while.
