A.First, I would suggest counteracting the effects of the vaccine with the homeopathic remedy Thuja, either 30C or 1M.
Demodectic mange is an immune deficiency disease. The mites responsible become out of control when the dog’s immune system is suppressed. Part of the problem is that cortisone and Ivermectin, which are being used to control the mange, are also very immune suppressing, so the cycle is perpetuated. In treating this condition, it’s important to build up the immune system. You could consider high levels of intravenous vitamin C as well as Chinese herbs. Seven Forest Viola 12 and Astragalus 10+ are both indicated for this condition and can be ordered through your vet. Thymus extract is another immune enhancer you could use, as well as flax seed oil and a good multi-vitamin. I would also recommend a veterinary product called Acemannan, an aloe vera extract that your vet can inject under the skin or in the belly. I have seen it reverse life-threatening demodectic mange cases. Topically, you could try tea tree oil.
