Clearly understanding that Chicagoans could benefit from having more random encounters with puppies in their lives, the marketing folks at Beneful Dog Food recently dispatched some canine couriers to deliver a perfect little package of happy to the Windy City.

A pup named Webster made the first stop (embedded above) at a nondescript Chicago office building -- and he hadn't even made it onto the elevator before finding a new buddy to toss his tennis ball in a video released early last month. In the next installment, Webster cheers up customers at a drab laundromat.

In the final of the three videos -- part of the dog food company's “Random Acts of Play” video campaign -- 11-week-old puppies hit some busy city sidewalks, giving curious kids, coffee slurpers and work-bound pedestrians a good old fashioned face-licking.
