Here's why:
* Color vs. Breed: Horse color is determined by genetics, not breed. While some breeds may be more prone to certain colors, there's no guarantee that all horses within that breed will be the same color.
* White is a "Coat Color" Not a Breed: "White" is a coat color, not a breed. A horse can be white and belong to many different breeds, like the Arabian, Quarter Horse, Thoroughbred, etc.
* "White" is Technically Gray: Horses that appear "white" are often actually gray. Gray horses are born a darker color and gradually lighten as they age, often turning white.
However, some breeds are known for having a higher incidence of white or gray horses:
* Friesian: This breed is known for its black coat, but some Friesians can be gray.
* Appaloosa: While the Appaloosa is known for its spotted coat, some Appaloosas can be white or gray.
* Lipizzaner: The Lipizzaner breed is known for its gray coat, often turning white with age.
Important Note: It's essential to understand that even within breeds known for having a higher incidence of white or gray horses, there are still horses that have other colors.
