I'm not sure about dragons, but Balrogs are maiar that Melkor corrupted.

Interesting point about dragons - who created them? Glaurung is called the father of dragons, and he didn't appear until Dagor Aglareb, if I'm not mistaken. But Morgoth coudn't have created him. Maybe he crossed a balrog with a lizzard and magnified the result a few times.

I wonder why/how/*I can't find the right word* did Eru give animals the ability to think and move on their own, just like Eruhini (except on a lesser scale)?
