Isolated demodedet mange need not be treated aggresively it is often a secondary condition the result of a slightly impeared immune system. It the area spreads then it does need aggresive treatment.


Demodectic Mange .

It is generally a disease of young dogs that have inadequate or poorly developed immune systems or older dogs that are suffering from a suppressed immune system.

...Fortunately, 90% of demodectic mange cases are localized, in which only a few small areas are involved and can often be treated topically. A treatment that has been successful for years has been a 1% rotenone ointment (Goodwinol ointment), or more recently, a 5% benzoyl peroxide gel applied daily. Bathing periodically with a benzoyl peroxide shampoo and feeding a high quality diet and a multivitamin with a fatty acid may also help some dogs. Most of these localized lesions will heal on their own and do not require overly aggressive treatment, though they may worsen before they improve.
If a dog develops generalized demodicosis, more aggressive treatment is usually required. Studies show that between 30% and 50% of dogs that develop the generalized form will recover on their own without treatment, but treatment is still always recommended for the generalized form.

FWIW 5-10% benzyol-peroxide is the active ingredient in many over the counter acne medications. and readily available.
