508 DOG DISTEMPER 



In other cases, there is a diffuse, parenchymatous keratitis 

 which renders the cornea, to a considerable extent, opaque and 

 gives it the appearance of ground glass. These extensive 

 opacities sometimes develop in a comparatively short time. 

 This affection of the cornea, the so-called "distemper of the 

 eyes," is frequently the only evidence of distemper with the 

 exception of the high temperature. 



There may be vomiting, well marked congestion and dry- 

 ness of the oral mucosa. There is usually constipation at 

 first, but later a diarrhea in which the feces, as a rule, are 

 very fetid, often slimy and froth}'. Hemorrhagic intestinal 

 catarrh sometimes exists. The urine frequently contains 

 albumin and bile pigment, especially when the patient is weak 

 or in an advanced stage of the disease. 



The nasal discharge is serous at first, mucous or purulent 

 later on. It is followed by sneezing, panting and a nasal pru- 

 ritis, which causes the animal to rub its nose with its paws. 

 The purulent discharge from both nostrils may be very copious. 

 It is sometimes mixed with streaks of blood, and varies in 

 color from a dirty yellow to a dirty green. Later, it may be- 

 come fetid and even watery. Ulcers may appear on the nasal 

 mucosa. 



Laryngeal catarrh usually accompanies the nasal catarrh 

 and manifests itself by a cough, which comes on in paroxysms 

 and which is at first hoarse and dry, but later moist and 

 accompanied by a discharge of phlegm. The cough excites 

 vomiting. The catarrh spreads from the larynx to the trachea 

 and bronchi. The resulting bronchitis is followed by an in- 

 creased rate of breathing and manifests itself by a cough and 

 hoarse, sharp, vesicular, respiratory murmurs. Frequently 

 there is a catarrh of the mucous membrane of the smaller 

 bronchi. There may be difficulty in breathing and a feeble 

 cough which the patients try to suppress. The cough may be 

 excited by percussion of the thoracic walls, by the animals 

 getting up and by their being taken out of their kennels. 

 Young and weak animals that cannot remove the accumulated 

 phlegm from the bronchi by coughing become affected with
