eh, shoot it with arrows till it crash lands then stab it with a dagger?
I guess the use of ranged dragonshouts as well
Who know, some towns might have built in ballistas that the guards/you can use?
Take advantage of your environment. By which I mean, find a place where the dragon's foot gets stuck in a rock due to a clipping error. It's how my character Raize won a near hopeless fight with a giant radscorpion in Fallout : New Vegas at one point
