DISEASES OF THE RESPIRATORY ORGANS. 215 



On stimulants, hygiene, and feeding must the reliance 

 be placed in extreme cases. Drugs are of subordinate 

 value. 



Convalescence is assisted by gentle exercise, sunshine, 

 massage, amusement, tonics, cod-liver oil, etc. 



It is well to keep records of the respirations and pulse- 

 rate, as any very markedly disturbed ratio should arrest 

 attention, and is by no means a good sign. 



Some additional remarks on each disease, to enable the 

 reader to grasp the salient features, will now be better ap- 

 preciated. 



Influenza. This disease, long known among men and 

 horses as an epizootic, is rarer among dogs, and is of very 

 varying degrees of severity. There is an inflammation of 

 the mucous membrane of the respiratory tract, beginning 

 usually in the nose and extending downward, sometimes, 

 especially in the debilitated and old, ending in pneumonia. 



The symptoms are altered breathing, frequent sneez- 

 ing, dryness, and burning sensation (if we may judge by 

 man's experience), with high temperature and great pros- 

 tration. 



Diagnosis. The eyes soon become affected. The 

 watery secretion from the nose and eyes, and the sneez- 

 ing, with the fact that the disease generally goes through 

 an entire kennel, will render the diagnosis easy. 



Prognosis. Favorable, if pneumonia does not inter- 

 vene, at least in vigorous animals. 



Treatment. Quinine, phenacetin, etc., with bromide of 

 potassium at the outset ; attention to temperature of the 

 dog's apartment and other hygienic conditions, to food, etc. 



If much depression, stimulants. Convalescence must
