Polcan and Shavka (1948)

Two dogs, Polkan and Shavka, watched a flock of sheep by the river. Suddenly, they notice a hare, chase after him and run into the forest, where they meet face-to-face with three wolves. Shavka, chickening out, backs away, and the brave Polkan takes the fight. In a fierce fight, he manages to defeat one wolf, but from wounds he loses consciousness.
