Beagles are used as detection dogs in the Beagle Brigade of the United States Department of Agriculture. These dogs are used to detect food items in luggage being taken into the United States. After trialling several breeds, beagles were chosen because they are relatively small and unintimidating for people who are uncomfortable around dogs, easy to care for, intelligent and work well for rewards. They are also used for this purpose in a number of other countries including by the Ministry of Agriculture and Forestry in New Zealand, the Australian Quarantine and Inspection Service, and in Canada, Japan and the People's Republic of China. Larger breeds are generally used for detection of explosives as this often involves climbing over luggage and on large conveyor belts, work for which the smaller Beagle is not suited.
