Here's why:
* Hanoverian horses are a breed defined by their specific bloodlines and characteristics, including their coat colors.
* Pinto is a coat pattern, not a breed. It refers to horses with large patches of white and another color.
* Hanoverians are typically bay, brown, black, or chestnut, with minimal white markings.
While there might be rare instances of a Hanoverian horse with some white markings, it's not considered a true pinto. A horse with a pinto coat pattern would not be registered as a Hanoverian.
