BORAX AND PEROXIDE AND PETROLIUM JELLY
I got the borax and peroxide remedy off of here and I added a few more steps to be really sure to kill the mange mites.
First, take a bucket of warm water and add as much borax as you can until it doesn't dissolve anymore. Then add a few ounces of peroxide. Then on the side, get a bowl and make a paste out of the borax laundry booster and peroxide. Then sponge the dog completely with the borax-peroxide dip. After that, rub the paste all over the dog and let it dry. Finally, rub some petrolium jelly all over the dog, to smother the mange mites. This is very messy so keep the dog outside, and do not wash it off. Repeat once or twice a week until the mange is gone. This worked wonders for my white boxer who had hereditary mange. Before, his skin was very pink with sores, and almost all his hair had fell out. Almost immediatly his skin and sores healed and his hair started growing back.
