Secret Service spokesman Max Milien told CNN the death was a “tragic accident.” The Secret Service dog was sweeping a parking deck near where VP Biden was speaking and fell from the 6 story platform and was shortly pronounced dead. The agency began its canine program in 1975 to detect explosives and uses Belgian Malinois because they are small and have short hair — making it easy for them to work in the heat. They are also very sociable. RIP.
