Labrador and Beagles were chosen by AFCD as the most suitable breeds for the friendly and outgoing detector dogs working around the public at the boundary entry points. In fact,each dog has been carefully selected to join the programme. Each dog can effectively screen more then 300 people per hour. Having an extraordinary sense of smell (said to be at least 100 times more acute than human being), they are gentle and cooperative with people and can remain calm even in the commotion at the entry points. As such, they have been well received by travelers who see them as welcoming and non-threatening. With quarantine effectiveness largely reliant on an informed and co-operative public, these dogs are of immense public education value.
