Как собаки зарабатывают на жизнь?

If you cross a jackal with a Siberian husky, you get a jackal-husky. Aeroflot passengers are unlikely to know that they are guarded by a unique breed of dog. These amazing animals have such a keen sense of smell that they can sniff out narcotics and even explosives hidden in luggage. Besides Aeroflot, no other airline in the world can boast such shaggy helpers.
