L A R YNG1TIS. 5 7 I 



In the chronic form of laryngitis we have a loud, harsh, ringing, and evidently painful cough, 

 easily induced by excitement, or rushing suddenly into the open air. There will also be heard a 

 stridulous or kind of crowing sound with inspiration. The disease may run on to ulceration. 

 The cough is often produced by the effort necessary to eat or drink. There is some little 

 tenderness usually evinced on pressing the larynx between the finger and thumb, a symptom 

 which, however, cannot be depended on, as dogs, if game, will frequently stand pain to a con- 

 siderable extent without crying out, so long as they know no harm is meant them. 



We have known a case of laryngitis produced mechanically in a large five-months-old 

 Landseer pup. It was caused by the dog being lugged along the highway by a thin rope, 

 which was passed round the neck. 



It must not be forgotten that laryngeal cough is sometimes of a reflex character, depending 

 on disease of another organ. At all events, in chronic laryngitis we nearly always find the dog 

 in a low state of health, and frequently suffering from loss of appetite and indigestion. 



Treatment. The object of our treatment must be to relieve the symptoms and strengthen 

 the general constitution. Sometimes, if there be much accumulation of mucus, an emetic may do 

 good, and give much relief; this only in the latter or moist stage, however. 



Mustard to the chest, lower part of the neck, and hot fomentations in short-haired dogs, with 

 the flat iron frequently applied to both sides of the chest in long-haired animals. 



The diet is to be rather sloppy at first ; oatmeal-gruel, a little beef-tea and milk. 



Take advantage of the animal's thirst to add to his drink a little of the chlorate of potash 

 and a portion of nitre. In convalescence give tonics, such as quinine or barks, with a little iron 

 and cod-liver oil. Blistering in obstinate cases may be had recourse to, but is seldom needed. 



If the disease lasts very long, which.it rarely does in dogs, and the cough will not yield to 

 generous diet and oil, the iodide of potassium will do good, with a castor-oil purgative once in 

 three or four days.

The disease sometimes resists treatment for a long time. Stimulating liniments and 

 occasional blisters (small) to the lower part of the neck often do good, and hot fomentations 

 when the cough is prolonged and very troublesome. Daily inhalations of steam (medicated 

 with tincture of iodine, one tablespoonful to a pint of water) do good, and all the more if 

 combined with a course of iodide of potassium internally. Give also cod-liver oil if the dog 

 be low in flesh. 



The bowels must be kept regular with either occasional doses of castor oil or with Gregory's 

 powder. If there seems to be much soreness of the throat, touch it daily by means of a 

 probang and sponge with a solution of nitrate of silver, three or four grains to an ounce of 

 water, or with equal parts of glycerine and tincture of iron. 



Some practitioners find they do good in these cases by making the dog wear a wet compress 

 of two or three bands of flannel, covered on the outside by oiled silk and leather, like a broad 

 collar. This may be tried, but we ourselves have found more benefit from the treatment above 

 recommended, and by attending in every way to the state of the general health. Arsenic and
