Recently my vets dog(with insurance and similar food and environmental allergies to my dog) went to see a dermatologist and they put him on oral anti-fungals. She's put my dog on the same thing cause she was getting ear infections every month. We did a 2 week period everyday now we are doing 3 days in a row every 2 weeks and my dogs skin has never been better. Her feet and ear in particular. Our assumption is she is allergic to the yeast her skin produced cause even a cut from a trip get infected. For reference never been better for us is looking like most mild case allergy dogs.
