Took her to the vet last week where she came back negative for mites. Her sister that my fiancés parents own has the same thing going on in both ears and was given medicine but I was not given anything for my dog. They told us that it was possibly food or allergies causing this before sending us out. It's gotten worse over the past few days and I'm really worried as sometimes she'll have a drop of blood that comes out when I wipe the outside of her ear. I accidentally made her yelp while cleaning yesterday and she was scratching a few minutes ago and scared me because she barked in pain. I'm not sure if it's sore from whatever is going on or raw from her scratching at it, but there is some sort of pain. Is there anything I can do to soothe her ear until I can get her in?
