 the neck stiffly stretched. Cough in these cases is violent, 

 spasmodic, and frequent. The saliva flows copiously from the 

 mouth, and the animal's paunch is distended with gas. The 

 breathing is very difficult indeed. The eyes are protruded and

 altogether is a picture of misery and distress. The offending 

 body can be felt at the back of the windpipe, and it protrudes 

 generally towards the left side of the animal.
