My dog has pneumonia, vomiting bile, and is tired. Is infection back?

Pet's info: Dog | American Bulldog | Female | spayed | 98 lbs

My dog has had pneumonia over a month now and finished her 3rd round of antibiotics on Friday. She seemed good yesterday but this morning is throwing up a lot of bile and seems tired. Do you think it's just the stuff she needs to get out of her lungs or the infection coming back?

Poor Hera! It is possible that her lethargy and vomiting are indicative of a persistent infection, but could also indicate a new gastrointestinal illness (virus, stomach upset from eating something abnormal, etc.). If she is actually vomiting bile, this is coming from her stomach and is not fluid in her lungs. Since this is her third course of antibiotics for the same bout of pneumonia, I recommend calling your vet today to address these new concerns.
