what did Dolly do in call of the wild

In Jack London's novel The Call of the Wild, Dolly is Buck's beloved lead dog on the sled team. She is a loyal and hardworking dog who helps Buck and the other dogs on the team pull the sled and transport goods. Dolly is a strong and brave dog who is willing to take risks and put her life on the line for the team.

In the book "The Call of the Wild" by Jack London, Dolly is a dog who is part of a team of sled dogs in the Yukon during the Klondike Gold Rush. Dolly's role in the story is relatively minor, but she serves as a supportive character.

Dolly is described as a friendly and gentle dog, often acting as a mother figure to the younger and weaker dogs. She is known for her affectionate nature and her willingness to work alongside her teammates.

Throughout the story, Dolly takes part in various sled dog tasks such as pulling heavy loads, navigating difficult terrains, and enduring the harsh weather conditions of the Yukon. She, like the other dogs, experiences a challenging and sometimes brutal lifestyle as they adapt to the demands of the wilderness.

However, as the story progresses, Dolly begins to show signs of illness, eventually contracting a viral disease called rabies. In order to prevent the spread of the disease to the rest of the dogs, Dolly is mercifully killed by François, one of the human characters in the story. Though her role in the book is relatively brief, her death serves as one of the many examples of the difficulties and sacrifices faced by the sled dogs during that time.
