Took Bear to the vet yesterday and he has a yeast infection in his ear. The vet said it could be just an isolated thing as it's only the one(moisture may have gotten in etc) but advised if it comes back we'll start looking at food & environmental allergies(she noticed his chin looked like he'd been rubbing it, it's spring here so maybe hayfever etc.). I'm sure I've read a few people on here have had dogs with yeast problems and I want to be prepared if it comes back and know how to go about the elimination process. I changed him over to a fish & potato food about a month ago and am thinking the carbs from the potato could be feeding the yeast - but all the dog foods I can find have either grains or potato as a binder. He also has environmental allergies, he came out in hives after running around in bushes a little while ago. I'm feeling like this pup is going to be trouble;-) any other natural remedies or advice on keeping yeast at bay? I know raw would be ideal but it's not really an option at this stage...
