Pregnant Dog

Hi Ted, My dog has ear mites. Your remedy for mange helped me so much that I though I'd write and ask your advice. She is a 2 year old pit bull and she's pregnant. I've been giving her vitamin e and vitamin c everyday. And, I've been cleaning her ears with warm water and peppermint soap every other day for the past 2 weeks, then I dry them and put olive oil mixed with garlic in each ear. I cannot tell if it's getting better. She still has the brown greasy discharge from both ears and now she has little red soars all over her face and in one part of her coat she had a brown spec of hair and when I cleaned it all of the hair disappeared making me think she has mange again. I can't take this, what do I do? I have another dog that NEVER gets sick. I don't want him to, but my female seems to catch everything.
