Dog Itchy Skin Home Remedy Options

I had dachshund, that broke out with a skin rash, also my R. Ridge back, the Dr's started them both on cordacoze I didn't really like using the drugs. One day one of my friends saw his bleeding around his neck and stomach and suggested corn starch I got a hand ful of cornstarch and rub his neck and stomach and the next day he wasn't bleeding and 1 week later both dogs and no signs of the rash it was great. I was so excited this was so amazing, and I still use it today.
