Wow, another case of a vet that robbed you and made things even worse besides wasting over 6 hours of your day. And 2k for xrays + a fecal ? Theis vet was trying to get more from you because your dragon does not need xrays. They are not even qualified to LOOK at a reptile. It would be good to put a review on their website for all to see. Anyway, try not to worry so much about the poo, and for now take your time to find a real reptile vet that has good reviews. Until then just be happy that he's healthy. He is not acting ill at all, many dragons have watery stools, it's just being well hydrated.
