oh she also did a demodex scrape just to be sure she has no demodex on her skin as she said no way she has scabies but demodex is a possibility so she scraped her down until she bled a little my poor baby and i prayed real hard no demodex as those meds are STRONG and she came back with no demodex thank God as my friend has been trying to kill this for 5 years in her yorkie and had a horrible time of it
