It could also be quite possible that Jon Snow himself finds out he’s a Targaryen this episode, and the title is an explanation of his true identity. In retrospect, he is a dragon and a wolf all at the same time. Lyanna was still a Stark after all and Rhaegar was a Targaryen – making him both wolf and dragon.
Twitter, of course, has their own theories:
It's titled "The Dragon and the Wolf"? Looks like uglies may be bumped, and I'm not referring to Cleganebowl. #GameOfThones

The Dragon and the Wolf. Title definitely hinting at a Rhaegar and Lyanna flashback. #GameOfThrones pic.twitter.com/UDoEjamm39
