Canine Yeast Infection

I noticed my French Bulldog Betsy has a distinct odor that has been quite unpleasant. She had been on antibiotics recently it likely caused a Yeast infection, which are usually smelly. I also noticed the constant itching as well, another sign of possible infection. Fortunately no lesions yet but want to be aggressive in heading off any long term problems. I understand Canine yeast infections are easy to eradicate and with the medications, but I am also considering supplements that may help in long term prevention and aiding her overall health.
