BRONCHITIS. 



Bronchitis is an aflfection to which dogs are very liable. 

 It may exist as a primary or secondary disease — i.e., it 

 may be present alone, or as an extension of catarrh or 

 other respiratory affections. Likewise it may be acute or 

 chronic. 



Causes. — Cold, damp, irritating inhalation, neglected or 

 protracted catarrh, or extension of other respiratory affec-

Symptoms. — These will depend on the extent of the 

 bronchial inflammation ; if the malady is only confined to 

 the larger branches of the bronchi, the breathing will be 

 much less disturbed than when the subdivisions are in- 

 volved, particularly the smaller ones. The cough in the 

 former will also be less frequent, louder and more sonorous, 

 with little or no expectoration. This form is, however, 

 rarely seen in the dog ; or, if so, only to be quickly suc- 

 ceeded by the 'more complicated one. I shall therefore 

 describe the general symptoms of the latter in its acute 

 stage. 



The respiration is hurried and difficult, the breath hot, 

 an incessant wheezing cough (which ultimately becomes 

 dry and short), succeeded by expectoration and vomiting 

 accompanying it. The expectoration is usually frothy, 

 and sometimes mingled with blood. The eyes are red and 

 inflamed, the nose dry and hot, mouth devoid of moisture, 

 tongue parched and coated with brown fur. The pulse is 

 quick and small, and the heart's action jerking. On 

 auscultation, the latter emits a thumping noise, and the 

 diagnostic mucous rattle of bronchitis is very distinctly 

 heard. A thin mucous discharge from the nostrils usually
