Diseases of the Respiratory Organs. 175 
tained within the chest of the dog is not usually, as in 
‘larger animals, confined to one in particular. The 
general tendency is for all to participate, while the inten- 
sity of disease is resident in one in particular—at least this | 
has been our experience, which is confirmed by other 
observers. It will, therefore, be more convenient as well 
as consonant with the view, to consider the several affec- 
tions as a whole, giving prominence to special manifesta- 
tions and conditions which may serve to render the 
elucidation complete. There is also much in common 
with reference to the needful treatment of the affections 
which will be given in usual course. 
The first indications, as a rule, are those of fever more 
orless severe. He pants and blows, being teased by a 
constant cough, the ears and extremities are cold, the 
coat in smooth dogs stands loose and staring, and fits of 
shivers recur at intervals of greater or less duration. The 
cause is not far to seek ; undue exposure to cold in some 
form or other is satisfattorily made out, and this probably 
not long after previous attacks of sore throat, nasal 
catarrh, &c. The systemic disturbance is now located in 
some part in particular, and there the chief manifestations 
will be found, while the whole of the respiratory organs will 
afford evidences of sympathetic derangement. 
Bronchitis, or Inflammation of the Bronchial 
Tubes, is denoted by accelerated but even respiration, a 
cough, probably dry at first but becoming moist, and 
attended with a discharge of mucus from the nose, as well 
as from the lungs during the act. As congestion of the 
lesser tubes within the lungs proceeds, the ejected fluid is 
also tinged with blood, the cough is severe: and frequent, 
and a wheezing or hissing accompanies the respirations ; 
the mouth, tongue, and nose are dry as well as hot, and 
the expired air is likewise indicative of a heated state of 
‘the lungs ; the pulse is accelerated, the heart-beats felt at 
the chest are strong in the early stages, and the tempera- 
ture, as shown by the thermometer placed in the rectum, 
is high, probably 103° or 104° F. Auscultation furnishes 
the mucous rattle as soon as the disease is established. 
From this point recovery is denoted by a cessation of the
