It takes a special breed to serve at the CIA. Actually several. K-9s, to be exact, that sniff out drugs and explosives both at the CIA and overseas in hot spots like Iraq and Afghanistan. There are 35 dogs in the K-9 corps, part of the Special Services Branch. But it's not all boring work. These dogs get to travel, sniffing around the Super Bowl and even the Olympics. And they star at local fairs, where playing cards of the pups are gobbled up like baseball trading cards at the All-Star Game. At one recent fair, over 2,000 cards of K-9 Agents Boris and Ringo were pawed out.
