Two big problems there.

One, there have been no indications that Dragons are a thing two Remnant aside from the Grimm. The characters didn't even know what to call the Dragon Grimm, implying that no reference points exist.

Two, the Grimm dragon has thus far been a unique Grimm, which indicates that this species of Grimm hasn't been seen in so long that even legends of it have at best faded into obscurity. The only people who had any idea of what was going on when it began to wake were those who working ofr Ozpin or Salem.
