Dragons can't be beaten
Some Dragons like Mythal and the Formless one can't be beaten.
They loose a 3rd of their life and after they get to higher ground it doesn't matter how much damage you deal. The life bar does not decrease.

on the first two it worked when I let my companions do the damage. Does not work on Fangscorcher though. He sits on top and is not loosing more health.
