That's unfortunate. It would be wild in the human world for a doctor to just give you a random medicine without finding out what is actually wrong. Unfortunately, that happens too often in the reptile world.We were not given a diagnosis
The vet probably suspected parasites, was a fecal test done at least?
The pictures I asked for up above will really help me and the other posters better offer help.
How old is Nutmeg? I'm assuming she is still young based on your comment about her needing to grow more. If so, she should be getting live insects more often then every two days. Ideally, a growing dragon should get insects daily alongside a salad.
What have her recent poo's been like? well formed? Loose? Liquidy?
