My bearded dragon has a yellow spot on his back and has had it for a few months now. He is eating well and is not acting strangely. It has gotten smaller as time goes on but I am still worried.

Hello, The yellow spot could be caused by several things like fungus, bacteria, or a skin mass. The fact that it’s getting smaller is good! Without an exam, I can’t tell you for sure what t is. However, I would be worried about something called “yellow fungus disease.” This is a potentially serious fungal infection common in bearded dragons. Diagnosis can be done by your veterinarian by way of a biopsy and culture of the affected skin. Sometimes, this infection spreads to other organs and can kill the dragon. Since you describe a small lesion, I would expect that if this in fact what’s going on, treatment would have a good chance of working. Therefore, I recommend taking Stalin to see a vet very soon so you can diagnose and treat early for the next chance of success. Good luck!
