Question: how to treat a dog's yeast infection in ears with apple cider vinegar?
Answer: If your dog is suffering a yeast infection of the ear the best ear cleaner is apple cider vinegar. Whip up a 50/50 mix of apple cider vinegar (the one with the “mother” in it, i.e. the bits, that's the good stuff) and warm olive oil (you don't used water as it feeds the yeast when not properly wiped out).
