Some dogs know that if they bark when their owners pull up in the car they're riding in at the drive-through window of the Worthington Northwest Library in Columbus Ohio, a person inside will open up the window and hand them a doggie treat. The window, introduced with construction of a new addition serves busy patrons who coast through to pick up materials they've placed on reserve. Library Manager Jeff Regensburger says about 50-60 people use the drive through each day and more so when the weather is bad/cold. Watch video here.
