Lara Logan gets a rare look into the secretive world of working dogs — some of whose capabilities are military secrets — and their handlers.

This week on 60 Minutes, Lara Logan took us into the secretive world of elite military dogs. These animals are not pets. They are “dogs of war,” and much of what they do for U.S. Special Operations and specialized units in the FBI remains classified. We know they can jump out of helicopters on a mission, capture enemies on the battlefield, and sniff out the kind of IEDs used by the Boston Marathon bombers. One of these dogs even helped Navy SEAL Team 6 capture Osama bin Laden.
