The true story about dogs at the end of the world, begun by Olga Shumkova in the story of the same name, continues. Dogs work in a cozy post office: they sort and deliver letters, bills and postcards. The youngest postwoman dog delivers correspondence to distant addresses. One fine day, a letter from Australia arrived at the end of the world, and a dog carried it to the addressee. This is how a story began that dramatically changed the life of a modest dog.
