The Dragon usually flies off and disapears after but i did once end up with two agressive dragons (and a Giant) somehow. I think you might have enought time to let your shout recharge but i'm not sure if you don'r ride them though they will quickly take off and patrol around you.

Experiment with it is the best way to find out anyway.
