Oxford Bookworms Library Level 3: The Call of the Wild

When men find gold in the frozen north of Canada, they need dogs - big, strong dogs to pull the sledges on the long journeys to and from the gold mines. Buck is stolen from his home in the south and sold as a sledge-dog. He has to learn a new way of life how to work in harness, how to stay alive in the ice and the snow and how to fight. Because when a dog falls down in a fight, he never gets up again.
