Just a little update, Belle got her weekly skin scraping today and it was negative! Last week, I found one dead mite.
If she has three consecutive negaticve scrapings, she can officially come off her demodex treatment. She is looking great. She's on the Thyroxine twice daily until October 10th, then she'll move to once daily. Then, a couple of weeks after that, we'll retest her levels and re-evaluate the dose of her medicine.
A lady from another board is looking into what she may can do about getting her into Dane rescue or something, which would be awesome! Please keep fingers crossed for her!
