I have had a lot of experience with demodectic mange. It can be done cheaper if your vet will allow you to do it yourself as mine did. It comes in a dip, you use just like you would a flea dip, by mixing it with water. What I used was mitaban, and it is very potent. You need to use disposable gloves and containers which can be disposed of, if you do it yourself. As mentioned above it can reaccur, though in my dogs I have never yet had it to. Where I am the mitaban was about $25 and was good for two dips. I also know from early experience, some vets will really try to get to you on this deal, trying to tell you the dip has to be done by a vet, but it doesn't, least not here. They will advise that it be though.

This is just from my own experience and my opinion. But my dogs got over it just fine from the mitaban and it cost me about $50 dollars total to do it.

However I do agree that a dog which has had demodectic mange should not be bred, as it is hereditary.
