Justin...I don't think it is mange mites...but if it is a bad case of mites then I would give a 40-60 pound dog 1.5 cc's of ivomec under the skin and the following week 1 cc under the skin and the week after that another cc under the skin again...
let us know what it is when you find out...
Mr. Reuben i will give that a try unless the bet says otherwise. And when i find out i will post what it was.
