Dog's ears get buildup of brown/black debris. Strong odor; have medicated for ear mites; seems to clear and then returns. Dog seems find and does not shake head or scratch. Ken
First you need to go to th evte b/c this may not be an ear mite problem. This could also be an infection, in which case the medication you are using will not help. I usually treat ear infections for 3 weeks. Good luck, vetcare
