The only thing that has worked for me through many years with dogs, is Lytar. It has sulfer and tar in it and it kills the mites. It only takes two or three washings. I wash them every other day for a week then one more for good measure about two weeks later. The tar kills the mites and the sulfer stops the scabbing and flaking. In really bad cases, it may take longer.
