We have several reports that mange has been controlled with cornmeal juice dips. In this case the solids don't even have to be strained away. Use about one cup of whole ground cornmeal or horticultural cornmeal per 5 gallons of water. I would also feed dogs Muenster Natural Dog Food and add the Missing Link as a supplement. I also agree that garlic powder added to the food is important and as well as apple cider to the drinking water at 1 tablespoon per quart.
