May I ask, how can you tell when he has aspirated anything? I know to look for signs of pneumonia (fever, lethargy, labored breathing, "wet" cough, etc), but how do you know he's aspirated before the pneumonia signs start to show? And what meds do you use to stave off infection?
(don't mean to hijack, but just had a laryngeal tieback done on one of my pups last week...)
