Last summer Vida started getting very head shy. I knew there was something wrong so I had the vet out and since she was so goofy about letting us look, we just put some antibiotic dust down in there.
I waited a few days and it didn't get better. I loaded her up and took her into his office. He sedated her and clipped the hair out of her ear. She had a tick way down it there that we couldn't even see without the clipping. He got it dug out and cleaned up. She was fine after that.
It's amazing how far down in the ear they can get, and what problems they can cause.
