Dragons are physically impossible in many more ways than the firebreathing. For one, things that large would probably struggle to fly. We can make larger things fly, but have to cheat using jet (or rocket!) engines to generate incredible thrust in ways not typically accessible to living beings.

That's ok, we just need to put them on the moon or somewhere else with lighter gravity.

You can make a setting with denser air and less gravity too.

And now I'm picturing a dragon with bombardier-beetle style pulsed jet boosters. And while I'd typically question your assumptions of how big dragons need to be in order to deserve the name, I'll assert that quetzocoatlus nothropi[1] was big enough.
