Gde ty, Bagira? Soundtrack (1977) OST

Returning from school with friends, Tanya saw a huge St. Bernard barking angrily at the kids from behind the fence. The girl was surprised by the dog's fierceness and invited her friends to retrain her. The first attempt to approach the evil dog ended in failure: Tanya's dress was torn, and her friends abandoned the idea altogether. But the girl nevertheless made friends with Bagheera and taught her many 'useful dog sciences'.
