Microhian Bronchitis in Dogs. 229 



In the same way all dogs, and especially such as have been ex- 

 posed, should be guarded against those accessory causes which 

 most commonly open the way for the entrance of infection. 

 Over fatigue, ice-cold baths, cold draughts when heated and ex- 

 hausted, damp, underground cellar beds, cold stone or iron sleep- 

 ing place, decomposing or insufficient food, ulcerative diseases of 

 the mouth or throat, starvation, low condition, debility from pre- 

 vious ill-health, and irritation of the air passages by irritant dust, 

 or gases, overheated air, smoke, etc., must be as far as possible 

 avoided. 



Treatment. The curative treatment must be that in common 

 use for simple bronchitis, with special attention to the use of an- 

 tiseptic inhalations or injections. The patient must be protected 

 against cold, outdoor, winter, or damp air, and especially rains 

 and snows ; currents of air must be avoided, and even customary 

 baths must be for the time abandoned. Yet the kennel must be 

 pure, sweet, and well-aired, and if this can only be secured at the 

 expense of a lower temperature a coat may be put on the patient. 



As a soothing agent use water- vapor from a jet of steam thrown 

 into the chamber, and an impregnation with an antiseptic (sul- 

 phur fumes largely diluted, carbolic acid, creosote, terpene, ter- 

 pinol, cresyl, oil of turpentine, eucalyptol, chlorine, iodine) will 

 greatly enhance its value. I,eaves of elder in decoction have 

 been used to render the water- vapor more soothing and diapho- 

 retic, and anise, poppy heads and even opium have been used to 

 serve a similar soothing purpose. 



Or direct expectorants may be given by the mouth, ipecacuan 

 wine, 10 to 20 drops, syrup of senega, a teaspoonful, or apomor- 

 phia, y^^ grain. Or ammonium chloride may be vaporized by 

 heat and inhaled by the patient. A hot, damp pack of the chest 

 with damp cotton covered with a dry dense material and maintained 

 in close opposition with the skin by elastic bandages will at once 

 sooth the bronchia and solicit expectoration. It can only be safely 

 used in a warm room and when taken off must be done one part at a 

 time, and the coat thoroughly dried and covered with a warm 

 dry wrapping. As an expectorant Cadeac recommends essence of 

 anise i gram, aqua ammonia 5 grams, alcohol 24 grams. A mus- 

 tard poultice on the sides of the chest will often serve an excel- 

 lent purpose, or they may be rubbed with common soap liniment.
