Sorry Hounds Man mange is caused by a mite, which is a parisite that lives off the the bodies of the host animal. It kills the hair folicals of the host causing the hair to fall out. It is obviously very uncomfortable for the infected animal and and it digs and scratches at any area on it's body it can reach to try and relieve it's discomfort. By doing this it opens sores that quickly become infected. I have acually seen animals so far gone that they smelled rotten,but were still alive.
