I have an older boa, after taking over her care and getting her back into health. My girl has developed spots that her scales have come off down to bare flesh, though scale rot has been removed as a possiblity as well as burns as she can't get close enough to touch her lamps. The rest of her looks fine but the two areas described I took her to a reputable vet (Dr. Fitzgerald) and he prescribed antibiotics. After 2 sheds, she still isn't showing signs of improvement. She's also had a hard time sheding despite regular warm baths. I have no clue what to do, the vet doesn't know what else to do either as her viral and bacterial tests came back negative.
