So, update...
I'd been using polysporin and Vetericyn on the skin outside of her ear, and my poor girl has been living in the
cone of shame. The sweet girl even seemed to get used to the cone. (I, of course, felt like crap.) I've also been pumping her full of Benadryl for two weeks.
My plan was to wait until the skin was completely white and no longer red and then I'd leave the cone off permanently.
This morning, her skin around the ear and in the ear looked normal. I took off the cone. She did good for a few minutes, and then she went at it...scratched like crazy drawing more blood in the ear and outside the ear.
I decided it was vet time. I took her in and they were super busy. Actually, they tried to blow me off by saying, "Just give her Benadryl."

I told them she's been on the stuff for almost two weeks!
Anyway, they looked at her (I left her there), and when I returned, the doc left a note that said this...
"I'm so glad you dropped Bella off with us today. It would have gotten much worse over the weekend if you waited. There is not a deep ear infection, but her outer ear (the "pinna") is VERY inflamed and just inside the ear. Not sure what started this. The redness around the ear is either from scratching or from an allergic reaction or both. The feet are red but not infected."
Then she prescribed Temaril-P tablets and Tresaderm Solution.
So, yeah...I've pretty much been torturing her for two weeks! How do you guys think this ear infection happened? I've been regularly cleaning her ears with witch hazel.
