"Equestria is a pony country. I don't know if there are any dragons living in it at all other than Joy, and if there are, they don't live in pony villages with ponies like he does. But there's dragons in other places farther away, and griffins, and certain kinds of sea monsters that can talk... I could probably look up a list of all the non-pony creatures who're known to use learnable language, but I might have to send away to another library in Canterlot for it."
