I just recently took my large sulcata for a check up. He is a large 77 pound 8yr old male. He seems happy and is eating just fine and he is also very active. But I did notice a whistling sound when he would breathe. The vet took xrays and said that there is a mild haze on the lungs. He said The tortoise might be developing something. And he put him on antibiotics for 2 weeks. I am taking him to another vet next week for further testing. Now im just super worried. Any advice?
