Herd Master
I have a cougher. We determined that after a vet check to look her over a few times but when getting herself a mouth of cud, she coughs. No fever, no nasal discharge, clear lungs, no parasites---it is just her and it drives me nuts.
However, I am always fast to inspect a cough because pneumonia is not something to mess with. First, I get temps and do a few to see if there is any change over the day. I then observe---are they hunched up, eating and drinking, isolating themselves from the herd? How frequently are they coughing? If there is a possibility of respiratory illness based on temp or observation, I call the vet and he usually puts them on antibiotics.
We've had a couple that the vet said the same something when they were regurgitating cud
