Warning: yeast is stubborn and does come back (the minute you stop looking for it) and it seems hot humid weather makes it worse. It remains a problem in her ears, but I emailed my vet and told him the ACV worked better than any of the shampoos and creams he had been prescribing.

Our 13-month old female Black Lab-Rotty mix dog Maya has been suffering from recurrent eye and ear infections for the last 7 months. When we first took her to the vet 7 months ago, the diagnosis was ear mites. We treated her with Revolution - twice. The infection seemed to get better at first, but then returned quickly. I then treated her ears with Yellow Dock for a few months, it seemed to keep the infection under control, but had not cleared it. Last month, Maya got a very severe ear infection and we took her to emergency - the test showed NO MITES - YEAST infection! It meant that I have been treating her all this time for the wrong cause - thanks to the vet who did not perform any tests the first time around and simply "guessed" that Maya had ear mites.
To cut the long story short, the emergency vet gave us some antibiotic cream, which helped at bit at first, but then we saw no improvement, especially around the eyes, so I found this website and decided to treat Maya with an organic ACV (half and half with water). I sponged her back (she had a few lesions there as well) and her ears twice a day, I let her shake and then wiped her ears dry. I sponged her eyes gently as well. Her eyes were circled by an elephant-like skin with no hair, and it seemed that like would never go away! Within 2 days we noticed a great improvement. I continued the treatment for a few days twice a day, and her conditioned improved 99%. I've read that it takes 3-6 weeks for it to clear up completely and that it is suffice to do it three times a week.
I measured her pH balance and noticed that it was too alkaline (around 8). This helps yeast to grow, so we started adding a bit of vinegar to her food to stabilie her ph balance. We've also implemented other dietary restrictions that are typical with yest
Overall, we've definitely found success with ACV, and I hope that other dog owners would be able to learn from us to help their furry kids.
