It can be rather heartwarming when a dog comes and sits by us. It seems all that we want to do is just cuddle with our new friend, but when this beagle comes and sits by you, it could mean trouble! He is a working dog and he helps to keep airports safe for all of us.
It is not only bombs or drugs that these dogs are looking for, they may find rather unusual items, such as food brought from another country. By coming over and sitting beside a bag that contains one of these items, they show security that something needs to be checked.
