Thank you I was going to ask how old she is , there is bacterial and viral pneumonia.In viral symptoms appear gradually and are less severe in bacterial they get sick fairly quickly and have a high fever and rapid breathing.With treatment bacterial is cured in 1-2 weeks..viral will last longer.There are vaccines now .The type of anti biotic depends on the type of pneumonia she has , as she has only taken the meds for a few days I would continue as prescribed but if indeed she seems worse and her temperature climbs it may be aswell to have her checked out again ..Good luck hope she better soon
