Distemper of Dogs. 



parts and dries around the nasal openings in brown crusts. 

 The secretions may also contain streaks of blood, or become 

 ichorous, and irritate the skin of the upper lip and of the 

 nasal wings, which then become raw. If the swelling of the 

 nasal mucous membrane is pronounced the respiration becomes 



sniffling (this is an 

 especially frequent 

 manifestation in 

 breeds of dogs with 

 short heads). 



The catarrh of 

 the larynx and the 

 bronchi is indicated 

 by a cough which at 

 first is short and dry, 

 later more prolonged 

 and moist. It some-

the animals greatly, 

 and also causes vom- 

 iting. Respiration is 

 accelerated and lab- 

 ored. Auscultation of 

 the thorax reveals 

 rough vesicular 

 breathing, and dry 

 or moist rales, as well 

 as other catarrhal 

 sounds. If in the fur- 

 ther course of the 

 disease capillary 

 bronchitis or ca- 

 tarrhal pneumonia 

 develops, the number 

 of respirations in- 

 creases to 60-80 and 

 even more per min- 

 ute. The accessory 

 respiratory muscles 

 are utilized to a 

 great extent, and at each expiration the cheeks become dis- 

 tended. In such cases percussion shows dullness, or a tjm- 

 panitic sound in places, while on auscultation, extensive 

 catarrhal murmurs are heard, in other places bronchial breathing 

 or no respiratory sounds at all are observed. The cough now 

 becomes very weak and feeble. 



The affection of the eyes mostly develops simultaneously 

 with the catarrh of the respiratory organs. It commences with
