Hello, I am taking care of my friend's bearded dragon. Almost two weeks ago she noticed what looked like tail rot and she started a treatment of betadine that's diluted in water along with Neosporin without pain relief. Her tail is a darker color still and I'm worried that it's getting worse. Can someone help me? If it helps, she is a baby. She was adopted on August 13, but we don't actually know when she was born.
