Here's why:
* "Milk white" is a coat color, not a breed. It refers to a very pale, almost cream-colored horse.
* Many breeds can be milk white. This coat color can be found in breeds like the Arabian, Akhal-Teke, Clydesdale, Friesian, and many others.
* White is a dominant gene. This means that even if a horse has one parent with the white gene, it can still have a white coat.
So, while there isn't a "milk white" breed, you can find milk white horses in various breeds!
