88 THE DISEASES OF THE DOG. 



may often be removed by reduced diet, increased exercise, 

 and tonics. 



Acute Lakyngitis is much less frequent in the dog 

 than the horse, and its effects are, in the case of most 

 breeds, of less importance. It occurs as a distinct disease, 

 but is most frequently a part of the state known as angina 

 or sore-throat. Fever runs high, there is a certain 

 amount of coryza, pressure on the throat at once causes 

 a painful hacking cough, the voice is either lost or very 

 hoarse, and the respiratory efforts are frequent. Snorting 

 has been remarked as one of the earliest indications. 

 Whether the disease be due to exposure, direct injury, or 

 extension of inflammation, it requires active treatment, 

 because it is most distressing and debilitating, and is very 

 liable either to chronically disorganise the laryngeal lining 

 membrane or to extend down the windpipe and involve 

 the bronchi and lungs in the inflammation. Serous 

 effusion beneath the laryngeal mucous membrane, ulcera- 

 tion, or chronic congestion are liable to remain after the 

 subsidence of more acute symptoms. The painful and 

 distressing condition known as laryngismus stridulus has 

 been seen in the dog. It is denoted by the sudden 

 occurrence of extreme difficulty in breathing, and a 

 crowing sound with each respiratory act. It seems to 

 depend on reflex spasm of the laryngeal muscles. 



Treatment of acute laryngitis although active must 

 not be heroic- It is a mistake to administer violent 

 emetics and cathartics — indeed, in bad cases the irrita- 

 bility of the throat renders it difficult to administer any 

 medicine whatever. In the acute stage the animal must 

 be carefully housed, kept in a warm, moist atmosphere, 

 allowed to inhale steam, and, where there is much distress, 

 a little chloroform. The throat should be freely fomented 

 and a stimulating lotion rubbed in, and enemata of milk or 

 broth with solution of belladonna extract should be given.* 



* Harms injected - 07 grammes of hydrochlorate of morphia in solution 

 subcutaneously in a dog with dry laryngeal congli of four weeks' standing. 

 Narcotism for two hours followed, but the animal gradually regained sensi- 

 bility, and in two and a half days left the hospital all right.
