110 DISEASES or THE HOESE. 



pleurodynia, or rheumatism, and other affections accompanied with 

 much pain, will grunt when moved, or when the pain is aggravated, 

 but grunting under these circumstances does not justify the term of 

 "grunter" being applied to the horse, as the grunting ceases when 

 the animal recovers from the disease that causes the pain. 



High hlounng. — This term is applied to a noisy breathing made by 

 some horses. It is distinctly a nasal sound, and must not be con- 

 founded with " roaring.'' The sound is produced by the action of the 

 nostrils. It is a habit and not an unsoundness. Contrary to roaring, 

 when the animal is put to severe exertion the sound ceases. An ani- 

 mal that emits this sound is called a "high blower." Some horses 

 have naturallj^ very narrow nasal openings, and they may emit 

 sounds louder than usual in tlieir breathing wdien exercised. 



WhistUng is only one of the variations of the sound emitted by a 

 horse called a " roarer," and therefore needs no further notice, except 

 to remind the reader that a whistling sound may be produced during 

 an attack of severe sore throat or inflammation of the larynx, which 

 passes aw^ay Avith the disease that causes it. 



CHRONIC BRONCHITIS. 



This may be due to the same causes as acute bronchitis or it may 

 follow the latter disease. An attack of the chronic form is liable to 

 be converted into acute bronchitis by a very slight cause. This 

 chronic affection in most instances is associated with thickening of 

 the walls of the tubes. Its course is slower, it is less severe, and is not 

 accompanied with so much fever as the acute form. If the animal is 

 exerted, the breathing becomes quickened and he soon shows signs of 

 exhaustion. In many instances the animal keeps up strength and 

 appearances moderately well, but in other cases the appetite is lost, 

 flesh gradually disappears, and he becomes emaciated and debilitated. 

 It is accompanied with a persistent cough, which in some cases is 

 husky, smothered, or muffled, while in others it is hard and clear. A 

 Avhitish matter, which may be cuidled. is discharged from the nose. 

 If the ear is placed against the chest behind the shoulder blade, the 

 rattle of the air passing through the mucus can be heard within. 



Treatment. — Rest is necessary, as even under the most favorable 

 circumstances a cure is difficult to effect. The animal can not stand 

 exertion and should not be compelled to undergo it. It should have 

 much the same general care and medical treatment prescribed for 

 the acute form. xVrsenious acid in tonic doses (3 to T grains) three 

 times daily may be given. As arsenic is irritant, it must be mixed 

 with a considerable bulk of moist feed and never giA^en alone. Ar- 

 senic may be given in the form of Fowler's solution, 1 ounce three 

 times daily in the drinking water. An application of mustard ap-
