rales. Generally both lungs are affected and the temperature 
is high and irregular. In lobar pneumonia the characteristic 
stages of engorgement, red and grey hepatization, appear. This 
complication occurs as a rule during the early convalescent 
period, and is ushered in with a well marked chill, followed by 
general fever, pain in side, furred tongue, scanty urine, which 
if examined for chlorides it will be found that they are decreased 
in quantity ; cough, thick glary discharge from nose and mouth ; 
discharge from nose may be tinged with blood, pulse full and 
quick, respiration hurried, and high regular temperature, aver¬ 
aging 105 degrees. 
In first stage no particular change on percussion, but upon 
auscultation fine crepitation, which is probably due to the bub¬ 
bling of air through the fluid with which the vesicles are filled. 
During the second stage or that of red hepatization, there is 
dullness over the solidified portion upon percussion, and upon 
auscultation bronchial breathing, absence of respiratory mur¬ 
murs and of crepitation, whilst percussion in the third stage 
gives dullness over the solidified portion and ausculation shows 
the same condition as in the second stage, with the addition of 
mucus gurgling. These signs vary, as often all three stages of 
pneumonia may be in existence at the same time. Usually only 
one lung is affected, most often the right, but both may be 
involved. 
Sometimes congestion and again oedema of the lungs occur 
as complications ; they are often associated with pneumonia. 
Pleuritis is manifested by the pain, fixed thorax, cough, the 
friction sound synchronous with the breathing due to the grat¬ 
ing of the dry pleural surfaces open each other. Fever, small, 
hard, rapid, “ wiry ” pulse—this often ends in • hydrothorax. 
Of course, as a result of pneumonia, gangrene or abscess of the 
lungs may occur, which would terminate the life of the dog. 
Cardiac Complications : Heart failure often manifests itself, 
but is rarely fatal except the pericardium is involved. As gas¬ 
trointestinal complications, I may mention pernicious vomit¬ 
ing, gastro-enteritis, intense abdominal pains, tympanites, haem-
