Hmm, if dragons bow to no king, then how come there have been so far two dragons that carry the title of king?

Igneel is the fire dragon king ( Enryūō ) while Acnologia is simply referred to as the dragon king (Ryū no Ō ) at this point in the story.

The other dragons that we know of so far have never been called kings, not even in their own element, which would fit with the whole dragons bow to no king if it wasn't for the two exceptions shown so far.

In the old days, when one didn't bow before a king ( even if it was a small bow ) it was generally seen as an act of arrogancy or an insult of some kind which wasn't looked on positively. But since these dragons apparently don't like to anger or insult each other as far as we've been shown, acnologia being the exception so far, it just looks a bit of weird.

Just something that struck me as curious with his statement regarding dragons.
