Seems like you and @ddnene are going through kind of the same thing I don't know of any home remedy's but I've read that stress can trigger it, also keeping his immune system strong will suppress it from coming back. Organic coconut oil and plain yogurt is something many on here including me put on their dogs food I think someone with more experience will come along very soon, it's not uncommon with Demodex mange unfortunately.
Found this info but not sure if it works... might be worth reading though I would consult my vet before using something since he's already on medication.
Home Remedies for Mange Mites on Dogs
Besides appropriate medication, certain home remedies can also be applied on puppies and dogs to provide them relief from soreness and uneasiness of mange.
1. Hydrogen Peroxide and Borax
Mixture of 1% hydrogen peroxide solution in borax powder and water is an effective home remedy for mange cure. Make sure that the mixture is thoroughly dissolved before applying it to your dog. Wash your dog once in a week with this solution, but remember not to wipe dry. If you will wipe the dog dry, the treatment will not show proper effect. Continue with this treatment for at least two weeks.
Note- Borax can make your dog sick if he ingests it, so use an E-collar to prevent the dog from licking it.
Honey is again an excellent remedy for treating mange mites on dogs and puppies. Honey can be applied directly to the skin of the animal, but remember to wipe it off by night; otherwise, the skin of the dog will be bitten by ants.
Apply two tablespoons of pure yogurt to the ears of the dog to deal with the problem of crusting and discharge due to mange.
