Diseases of the Respiratory Organs. 37 



"Symptoms. — As to the symptoms produceci by the worm, 

 whilst Rudolphi found a dog which he examined perfectly 

 well, and Dujardin, Miram, Colin, etc., make no reference to 

 any disorder in their cases ; on the other hand, Chobart 

 gives rather a dark account of the effects produced. ' The 

 animal,' he says, 'is subject to convulsions, during which it 

 is violently agitated, stops short, hits itself on the head, 

 rolls over, rubs its nose on the ground, and the jaws are 

 convulsively champed. It devours everything within reach, 

 such as wood, straw, etc., discharges a large quantity of 

 saliva, passes urine involuntarily, and sneezes without 

 •ceasing. Death sometimes ensues.' 



"The mucous membrane of the nose is found to be red, 

 "blackish, ecchymosed, thickened, and ulcerated ; the sinuses 

 more or less filled with pus ; and even the ethmoid bone 

 sometimes partially carious. 



" Treatment — Trephine the nostrils and inject with water. 

 Inhalations of chlorine and tobacco smoke. Chloroform?" 



ASTHMA (Congestive). 



This disease is due to congestion of the mucous mem- 

 brane of the bronchial tubes, and chiefly affects aged, highly 

 fed, pampered house-dogs, and those in the same condition 

 out of doors. 



Predisposing causes. — Hereditary disposition, indigestion, 

 gastric and intestinal irritation. 



Exciting Causes. — Sudden changes of temperature; flatu- 

 lency ; obstructed pneumonic circulation ; large accumula- 

 tions of fat, especially about the heart and large blood- 

 vessels ; pungent effluviae, especially ammoniacal : hence 

 dogs continually kept in foul stables being asthmatical. 



Symptoms. — Thick, laboured, wheezing respiration ; 

 husky bark ; distress after exertion, with excessive panting, 

 and frequently palpitation; Schneiderian membrane in- 

 jected ; flatulency and constipation.
