Aw, skinny little creature.
Good thing you got a hold of her. What is your feeding/
hydration routine ? Remember, not too many insects , just a few soft bodied ones that are not large size. Slurries with greens + a few bugs if you want, make them tasty for her + add extra water. Water on the snout daily if she'll drink. Set a shallow plastic lid under her chin while in the tank and spray [ gently ] or drip water on her snout tip that will drip into the shallow lid. Many
thirsty dragons will lowr their head + drink.
But again, if she gets a good slurry several times a day [ you can add a bit of Pedialyte as well, optional ] that should help immensely. Best wishes that she'll bounce back in time.
