X6 CANINE MEDICINE AND SURGERY 



Symptoms. — The manifestations of chronic laryn- 

 gitis are the same as of the acute form, but are 

 much modified in intensity. The cough is not so 

 easily excited, but is hard and dry, and is usually 

 worse at night, being often of a spasmodic nature. 

 On manipulation, the larynx is not so tender as in 

 the acute form of the disease, though coughing can 

 be produced by pressure upon it. Exercise and 

 excitement likewise produce attacks of coughing, as 

 does also exposure to cold winds or draughts. 



Treatment. — This, as a rule, is not satisfactory, 

 but should consist of sedatives, to allay the cough, 

 and stimulant inhalations, such as steam medicated 

 with turpentine or oil of eucalyptus. Medicinally, 

 guaiacol in oil may be given, and the patient should 

 be placed on a good tonic course and liberal diet. 

 A sharp counterirritant over the laryngeal region 

 is also of benefit in some cases.
