For the past week and a half I've been giving her baby food thru a eye dropper. Which seem to keep her hydrated for a little but then goes nack to be lathargic. She is or was dehydrated but I will stop giving her babby food so she will be hungry enough to eat greens but worried she would hold out to long and get dehydrated again. She only eats bugs. But is a year old female.
She looks pretty good in the photo. Has she been pooping regularly? The poop is usually a good indicator of hydration. If it's not dry/chalky then she is probably OK.
It depends on the dragon really. If they are healthy and a good weight they can hold out for a while. If they are too heavy it's not the best idea to do that too long and wane them off by offering fewer and fewer bugs so not to stress their systems. That might be a good option to try as well.
