Thanks! The time the vet said she thought Lily was having allergies it actually turned out to be fleas. (Apparently the frontline plus wasn’t working.) We have since changed to Activyl which took care of the problem, though she had a few more fleas 4 weeks later right before the next dose. She has still been sort of itchy though, which promoted us to think it might be allergies. The vet initially prescribed an anti-hisimine, which we chose not to use because she had recently been on antibiotics for an anal gland issue (one reason the vet suspected allergies.) and wanted to see how she would do without any medication for a few days. Then, we figured out the problem was fleas, and so we decided not to use the antihistamine at all. We also changed her food, from TOTW Wetlands to Lotus Grain-free Duck. She still seems somewhat itchy, mostly on her face.
On a side note, I just realized how much I use parentheses. Somehow I never noticed that before.
