While the word "fur" is often used to describe the coat of animals, it's technically more accurate to call it hair in the case of horses.
Here's why:
* Fur is typically denser and thicker than hair, and it's often found on animals that live in cold climates.
* Hair is generally softer and finer than fur, and it's more common in animals that live in warmer climates.
While horses have a thick, warm coat during winter, it's still considered hair because it's softer and thinner than the fur of animals like bears or foxes.
