HARTSDALE, NY - JUNE 10: Rescued dog "Brownie" attends a memorial service for military working dogs at the Hartsdale Pet Cemetery on June 10, 2012 in Hartsdale, New York. Shelter Pet Alliance held an adoption event for some 60 dogs and cats in Westchester County annimal shelters during the annual memorial service. Thousands of dogs have served in American military conflicts since World War I, most recently in Afghanistan detecting roadside bombs and mines meant for U.S. troops. The cemetery, established in 1896, is the oldest pet cemetery in the United States and serves as the final resting place for tens of thousands of animals. (Photo by John Moore/Getty Images)
