Is there a Latin name for miniature horse?

There isn't a specific Latin name for "miniature horse." Here's why:

* Latin names are scientific: They're used for classifying species, and miniature horses are not a separate species. They're a breed of horse (Equus caballus).

* Breeds don't get Latin names: Latin names are for species, not specific breeds within a species.

So, the Latin name for a miniature horse is the same as the Latin name for any other horse: Equus caballus.

However, you might find some breeders or enthusiasts referring to miniature horses using the Latin name for their specific breed. For example, the American Miniature Horse is sometimes called *Equus caballus* var. *americanus*. But this isn't officially recognized.
