Hmm, I can't seem to see anything from that picture. So let me tell you about my vet visit today. I wasn't satisfied. In short, the doctor said that it "could" be ear mites and I can try putting on mineral oil and see if that works. Also, the mites should be more obvious on the inside of the ear instead of the outside. But because Fudgy is only 14 oz (she's only about 2 months old), the ear mite treatment shot will be too small of an amount to inject (like 0.05 mL) so she was against that. Then she gave me a mixed solution of tresaderm and ivomec___(something) and told me to apply it to Fudgy's ear 1-2 times a day. Basically until she gets larger, there isn't really a way to know...
I wish I had a better diagnosis for you. I'm contemplating taking Fudgy to another vet and getting a second opinion.
I guess if it gets worse, take Ginny to a vet and see what they can do about it?
