The Sarcoptic variety of mange is an interesting disease.. I just read up on that one. It differs from the Demodectic mange in that instead of the mites living inside the hair folicles, the burrow anywhere in the skin. These "Sarcoptes scabiei" mites can also transfer to people - kinda scary. But for some reason I couldn't find, they can not sustain life in human skin like they can in dogs.. instead they burrow down and die. Something else that I found interesting, which may be a dumb thing, but some dogs can actually grow up without Mange.... Since they are transfered thru contact with the mother, the puppy that gets pulled away directly after birth can grow up without it all!
Anyway...
