She takes inhaled corticosteroids but this persists and the vet is just no help.

What can I do about it, do i need to put her in a damn head cone?

Edit: im going to try her on an oral steroid for a little bit and keep up her inhaler schedule going while i go nuclear on sanitizing the environmemt.

I threw out all the fabric-type things like mats and carpets and stuff like that and swept and mopped a ton and it does seem like its calming down a bit
