There is a lot of misinformation out there on Demodectic Mange....
One of my dogs (seen in my avatar) had mange and we finished the treatments about 2 months ago.
When we first started, I did a lot of research to find the best possible course of treatment for her and decided the mitaban provided the best chances for recovery (in conjuction with an immu-boosting supplement).
This is a great site to find out about it.

As you will read...it is genetic. All dogs have the mites but a comprimised immune system causes the "red mange".
If there is anyone out there that is dealing with this at the beginning, I would be happy to share my experience and my treatment log. Just pm me.
