A mitey big problem

I am appealing to you for herbal help with the problems my French Bulldog bitch has with Demodex. I have great faith in my own conventional vet, but he admits that he has no training in herbal advice and I understand that the drug he is using for her shampoo will kill the dog before it completely eradicates the mites causing the Demodex. It can only be kept under control until the next time the mites cause the dog further irritation, when a further session of drug baths will again be necessary. She is not yet three years old and has just completed her third session of weekly baths, eight the first and second time, and six each of the third and last time. The first of each session involved an anasethetic to enable a scrape to be made and count the mites in the blood sample taken.
My vet advised me that Demodex is inherited from the mother, either as a sufferer or carrier so I wrote to the breeder and received a letter back stating that their bitch did not suffer from anything and they did not know anything about the sire!
Why is her natural immune system not coping with this problem? If you can cure this Demodex with a herbal remedy I should be very grateful for your help.

A mitey big problem
It is impossible to prove but I believe that improving the general diet can provide a less hospitable environment for the mites and boost the ability of the body to kill them off. A diet based on whole grains, low in fat and protein and fed as sparingly as possible can be helpful.
