Only one chemical I have found seems to be effective and that is permethrine...problem is my dog is allergic to it. It has been quite a battle but i finally won it by using very small doses of it and doing it 4 times a month.
It has happened several times...he's 11 now, but I am trying to give him a few more years. The mite bites humans as well, vet told me it is of the type that crosses species..difficult to eradicate and this part of the country is crawling with the stuff..
Part of the after effects, is a thickening and blackening of the skin and loss of hair, all the hair..
Using cortisone's, off the shelf, and believe it or not, Dynovite....
He's been on the dyno for 6 weeks and all the hair is back and the bad skin is falling off replaced by new skin and hair..
I have never tried to use a dietary aid until now, as I was afraid I might lose him. So I bought the stuff and darn glad I did...
Try the Nu-Stock.
