A one year update: So about a month ago, to my surprise, she started itching more than usual, and when looking over her, I found another dead patch of hair again on the back, just above her tail. Pretty close to where it was last year. I was blown away it had come back almost exactly to the year. Nothing on her ears though.
I figured maybe it's like GatorBytes above said happens to her dog every year, at the same time, and it's something to ignore.
So we went in to the vet anyway, as she was due for her annual, and we were checking her out, and looked under her belly as well, as I had seen some scabs there, and then we see this little black flea running across her tummy!
So the vet now thinks that it's a flea bite that she's allergic too, and most likely, last year was the same thing, though oddly enough, we ran all these tests on her and took scrapes and checked for fleas, but nothing showed up. She said though unless you get lucky and the flea is picked up in the scrape, it is hard to pick up in the tests.
So we put her on two doses of Advantage II, and I will proactively give her two doses next year in early September, which is when flea season here starts. I think it makes sense, as last year, we ended up putting her on two doses of Revolution, which is for both sarcoptic mange and fleas, and the problem did seem to clear up after, come to think of it.
So it seems at least the mystery is solved! Phew!
