Again I'm not familiar with the meds she's on. But if she appears to not be getting better I'd speak to the vet. I'm a huge baytril fan it's literally knocked out 3 majiorly bad RIs I've had in my whole bp ownership time. 2 were awful and the third was a pretty low grade. But if still talk to him. The meds may need to be changed and if that's the case he should be aprised on her progress. If she seems to be getting worse then another day or the third injection won't do much. I'd speak to him asap tomarrow over the phone and see what he thinks should happen.
