Most antibiotics are either 7 days or 14 which is hers? And most vets and doctors will say to finish the course. After she is done, I'd give her a probiotic to put back the good bacteria that the antibiotic killed along with the bad bacteria.
When my Runner had a bad case of bumble she was on an antibiotic for 14 days I did give her a probiotic after. Such great news to hear she looks so good and is back to normal.
