How many different breeds are there for paint horses?

There's a bit of a misunderstanding here. Paint horses are not a breed in themselves, but rather a *color pattern* within various breeds.

The most common breed associated with the Paint horse is the American Paint Horse, but other breeds can also have the Paint pattern, including:

* American Quarter Horse

* Thoroughbred

* Appaloosa

* Morgan

* Arabian

* And many more

Therefore, it's impossible to give a specific number of "Paint horse breeds." The focus should be on the color pattern, not a breed.
