Diseases of the Respiratory Organs. 17$ 



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. 



lih-Q 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 satisfactorily 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
