I live in KY as well and I have horrible allergies. They get worse as I age.
I really hope that Karlee is not the cause of these outbreaks. Poor baby. If she knew that she was causing it, I know that she would try everything she could to stop it b/c I am sure she doesn't want to part with you.
Let me know if I can help in anyway. Whether that is fostering for awhile, helping to rehome, etc. But lets hope and pray it doesn't come to either of those!
