Liz,

There are 2 types of mange. Demodectic and another one that I can't think of the name of right now. Demodectic is treatable and not contagious, it is, however, never going to go away if the dog has that kind. I guess all dogs are born with the demodectic mite (well actually they get them from their mother soon after birth), but some have a compromised immune system and can't fight off the mites and so are destined to continue to have them all their lives and it comes and goes. Dudley has demodectic and was fine until just recently and he is losing hair again, so Dr. B has him on Keflex (sp?) again to ward it off, we'll see what happens. The other kind of mange is contagious, but as far as I understand, is gone once it is gone. Please let us know what happens.

Molly
