Call me crazy, but singers sip honey tea because it coats their throat and vocal cords... Think you could convince her to drink some and see if it helps?
It sounds to me that if she hasn't had reason to bark in 2 weeks, then she should have made significant improvement. I might would talk to a vet.
Tiny, she made improvement. When I brought her home 2 weeks ago she couldn't make a sound. Today, she barked strong to start but voice quickly started sounding weak and hoarse. But yea, your probably right, I'll talk with vet.
