A three-year-old Belgian Malinois attack sniffer dog named Cisko patrols for explosives with U.S. security forces guarding Washington's ambassador to Afghanistan, Zalmai Khalilzad in Kabul August 8, 2004. Cisko's sniffing abilities make him worth an estimated $60,000, more than the price of a Corvette sports car. REUTERS/Ahmad Masood AM
