In George Orwell's Animal Farm, we have three prominent horses involved in the story.
The two most frequently mentioned are the cart-horses Boxer and Clover. These two horses represent a mature, hard-working couple. Neither Boxer, the male, nor Clover, the female, are very smart, but they are very loyal, as evidenced by one of his mottos "Comrade Napoleon is always right" Not only are these two horses loyal, but Boxer was "as strong as any two ordinary horses put together." Boxer's motto, when anything goes wrong, is "I will work harder!" Even when Boxer is wounded in battle, he will not take a day off of work. Boxer's death in Chapter 9 is a moving and troubling moment in the story.
After Boxer's death, Clover continues to pass on information about "the principles of Animalism" and is a respected teacher.
The third signifcant horse mentioned in Animal Farm is a young mare named Mollie. She is like a young, teenage girl who is only concerned about what she will eat and what her personal appearance is. She is also a poor worker and would often make some excuse to get out of doing work. She also refuses to learn any letters except the ones that spelled her own name. In Chapter IV, she is found hiding in the barn during the humans' attempt to recapture the farm. In Chapter V, it appears that Mollie has become a traitor to the animals. She soon afterwards disappears and was never mentioned mentioned again by the animals.
