Dmitriyev started writing about animals. His first story, which was published in the newspaper Moskovsky Komsomolets and was entitled The Green Patrol, was about nature and animals, and already in this first book Dmitriyev did his best to infect boys and girls with his own love for nature and his dedication to its protection.
