e over driven are subject to Lung Congestion in
acute or chronic form and sometimes Pulmonary Apoplexy, and especially
when in a plethoric condition are predisposed to inflammation of the
lungs. The exciting cause is very much the same as in different diseases
of the air passage and it is not uncommon for the inflammation to extend
from these parts of the lungs. However, there are a number of causes in
addition to those already mentioned. It frequently results when sheep
are accustomed to warm, comfortable quarters and are changed to cold,
drafty pens, or shipping some distance in open stock cars during cold
weather. In fact, any sudden chilling of the body is a common cause of
lung disorders. Giving fat sheep too much exercise when they are not
accustomed to it is a very frequent cause of Congestion and Inflammation
of the Lungs. This may occur when they are chased by dogs, etc., or when
driven to a distant market at too rapid a gait. Exercise during the hot
summer months is apt to cause congestion of the lung substance, as well
as heat stroke. Dipping sheep during cold weather may chill the body and
result in this disease.

SYMPTOMS: If due to severe exercise, the animal appears greatly
exhausted and the Congestion of the Lungs is marked. Death may occur in
this stage of the disease. Inflammation of the Lungs usually begins with
a chill and is followed by a high fever. The sheep stand most of the
time and may eat nothing, or very little. The breathing is hurried at
first, but when the lungs become badly involved, it is also labored. The
character of the pulse beats varies, depending on the extent of the
inflammation and the stage of the disease. In most cases the pulse is
full and quick during the early stages of the disease. A very weak pulse
is present in severe and fatal cases of Pneumonia. The visible mucous
membranes have a red colored appearance and there may be a slight
discharge from the nostrils. The expression of the face is anxious and
distressed in severe cases and rigors and chilling of the body occur.
The respiratory sounds are more or less normal. The cough at first is
deep and dry; later it becomes loose and moist. It may be accompanied by
a hemorrhage during this stage of the disease. Other respiratory sounds
are revealed by placing the ear to the side of the chest walls and
listening to the sound of the lungs. This cannot be practiced in long
wooled sheep with satisfaction, as the chest walls are so t
