Chronic Cough. 
A trouble of this character among stock is quite common 
in the United States and is of much more frequent occur- 
rence in animals which have but little or no advantages in 
the way of pisture than where they have free range upon 
either prairie or meadow. 
Cause—The cause of this trouble is largely a matter of 
co. jecture but it is reasonable to suppose that it is brought 
about through an inflammatory condition of either the lar- 
yux-or bronchial tubes, these being constantly irritated and 
kept in this condition by the presence cf dust in the feed 
or atmosphere. Some writers claim and I am not prepared 
to refute it, that these coughs are sometimes brought on by 
neglect and improper treatment of catarrh and distemper. 
HOW TO KNOw IT. 
The cough is recognized as being dry, husky and hack- 
ing. Where in health it is strong and fnll and usually fol- 
lowed by a sneeze to clear the nose. It may be that the 
animal thus affected will cough but little at a time, and 
again he may have a spell of coughing lasting several min- 
utes, followed shortly by another spell of like character. 
This cough can in some cases be brought on by pinching 
the larynx, and in others speeding of the animal is neces- 
sary to develop it.
