Yes, but dragons breathe fire. That has to be coming from somewhere inside them, hence my use of ‘furnace’.
 
That and given that dragons are reptiles, it might be they’re more closely related to birds (like crocodiles) than lizards. And birds can usually handle cold temperatures fairly well.
 
EDIT: I have to admit, I kind of agree with Garble’s attitude when the real cold and snow and long nights come. I always love to see Spring come.

yeah all you need is a hat a scarf and some gloves and boots to be warm

Lizard are cold blooded

Garble has his own internal furnace. Would he even feel cold?

Garble is not amused.

“I’m not going back outside until I stop seeing my own breath out there.”
 
So, no more firebreathing?

This should’ve been in an episode.
