Which animal is often associated with physical strength and work ethic on the farm?

Boxer is the character best known for embodying physical strength and an exceptional work ethic on the farm. As a cart-horse, he is depicted as hardworking, loyal, and dedicated to the farm’s success, epitomizing the ideal laborer. His famous mottos, "I will work harder" and "Napoleon is always right," showcase his determination and unwavering support for the leadership of the farm, reflecting the themes of labor and sacrifice in the story. Boxer’s character serves to illustrate the exploitation of the working class, as he works tirelessly for the benefit of others while ultimately being let down by those he trusts. This makes his association with strength and work ethic particularly significant within the narrative. The other characters, such as Benjamin, Daisy, and Pigeon, do not have the same direct focus on physical labor or work-related themes in their roles.
