Bo has been sneezing again, and blood in her mucous. It's still coming out only one nostril and now she's shaking her head a lot. I'm wondering if she doesn't have an ear infection, along with whatever else is wrong?

She has a vet appt. tomorrow at 4:45 p.m. I'm stressing, since she's had this problem ever since we brought her home from the park. Last time they said it was e-coli and put her on antibiotics.
