Dov is used to refer to all dragons, or dragonkind (the dragon species). Dovah is used to refer to a single dragon. The plural form of Dovah is Dovahhe.

You would use dov when referring to dragons as a whole, and dovah when referring to a specific dragon. For example, you might say "The dov are the most powerful creatures in the world," but "The dovah attacked the village."
