My 6 month old female has pneumonia and I was prescribed Doxycycline. It's been 6 days now. It seems like it has helped a little but the problem is she is no longer eating. The 2 times she has tried to eat she threw up. Anyone have experience with Doxycycline? I'm considering switching to Baytril but wanted some feedback from anyone who's used Doxycycline or had similar experiences. Thanks
