Some people think that a dragon attack can only happen inside of a walled city if the dragon spawned while you were outside and followed you in. In other words, you are to a degree in charge of whether or not a dragon attack happens or continues within a walled city. This also means that if you rush to leave a city while a dragon is in the walls, it should follow you out.
I have never encountered a dragon within a walled city, so I can't comment first-hand on this theory.
