Do you know whose job is to stop food from going from one country to another? B-E-A-G-L-E-S! Do you know why? Because these dogs love food. They are perfect for the job.
Beagles work at airports in a lot of countries, such as Canada, the United States, Australia and New Zealand. Their job is to sniff (嗅) out food. These special dogs have special noses. They can even smell food in bags or boxes. When a dog finds a bag with food inside, it sits in front of the bag. If the dog finds the food, the workers will give them something good to eat.
These dogs don't live in a house because the food in houses distracts (干扰) them. Their noses are very important. Living away from people helps to protect their noses.
These working dogs should not be afraid of large groups of people or other dogs. They should not be afraid of loud noises. They should feel well when travelling in a car.
Next time when you're at an airport and see police dogs, don't play with then. They are busy. They're working to keep us safe.
