Hi, I’m Dr. Aimee Beger. I’m a veterinarian, and many people use athome remedies to treat dogs with ear infections, or debris coming out of the dog’s ear. One common method at home is to use apple cider vinegar. The remedy is typically made by one tablespoon of apple cider vinegar in one cup of warm water, and to use that as a flush to kind of flush out any debris or objects in your dog’s ear. Here, we typically don’t recommend that, because it can sometimes be very caustic, or burn an inflamed or already bleeding ear canal.
