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— Arthur (@Flasheart88) August 23, 2017
oh my god im praying 'the dragon and the wolf' means rhaegar and lyanna's story and NOT the weird incest jon/daenerys ship pic.twitter.com/SuBrYO72tr— ˗ˏˋ reena ˎˊ˗ (@KlNGTAEYEON) August 23, 2017

I think Jon Snow will finally "Know Something"
the wolf and the dragon refers to rhaegar and lyanna, jon and daenerys, and jon being both a stark and a targaryen pic.twitter.com/yuoXMz7eLZ— gab | finale! (@eastswatch) August 22, 2017
What’s the true meaning? We’ll just have to wait and find out – in 80 f*cking minutes.
Can you say – hyped?!?
