Have you ever wondered who helps stop food from being secretly(秘密地) taken from one country to another? Beagles(比格犬)! Why are they so good at this job? Because beagles love food and have amazing noses. They are great for this job.
Beagles work at airports(机场) in many countries, such as Canada, the United States, Australia, and New Zealand. Their job is to find food hidden in bags or boxes. When a beagle smells food, it will sit in front of the bag to let people know. If it finds food, the workers will give it a treat(零食) as a reward(奖励).
Beagles don't live in normal houses because the smell of food there can distract them(让它们分心). Their noses are very important for their work. Living away from people helps keep their noses strong. These working dogs need to stay calm(冷静的) when they hear loud noises and when they travel in cars.
Next time you see police dogs at the airport, remember not to disturb them. They are working hard to keep us safe.
