PREVENTION, SYMPTOMS AND TREATMENT 37 



trouble (p, 39) should be given. Other lesions should likewise be 

 attacked according to their- nature. 



True bronchial asthma of. dogs, occurring in definite attacks as 

 a neurosis, described above, must receive treatment which shall have 

 three objects: (1) To remove attack ; (2) to allay the severity 

 of the attack; (3) to prevent or lessen the severity of the attacks. 

 Prophylaxis must be directed to the causes already mentioned: 

 During the attack, relief- is 'secured- by a variety of drugs, as 

 inhalation of chloroform or amy! nitrite (ntiii-v), injection, of 

 morphine sulphate (gr. %^/z), with atropine sulphate (gr.. 1-150- 

 gr. 1-100), or the use of chloral hydrate (gr. x-xv) with sodium 

 bromide in twice this amount in -solution, for dogs. For horse's, any 

 one of the same agents is indicated, or spirit of chloroform, gi, in 

 §ii of whiskey. 



Following an attack treatment should be directed- toward cure 

 of the trouble. The iodides and belladonna are the two most 

 useful drugs. Thus, to dogs, potassium iodide (gr. x)i may be 

 given in solution with tincture of belladonna (lUx) thrice daily. 

 Horses will receive 2 drams of the iodide with; 1 dram of fluid 

 extract of belladonna. The addition-of potassium bromide (gr. x to 

 xv ) to the iodide mixture is sometimes serviceable in dogs. Inhala- 

 tions are of value. 



During an attack the fumes of burning stramonium leaves 

 and' saltpetre may avert the seizure. Inhalations as recommended 

 for bronchitis (see p. 38) are also of great value. Tonics, es- 

 pecially to the nervous system, as arsenic, may be of worth, and, 

 fats or oil in conditions of inanition. Dust is to be avoided and 

 a digestible and concentrated diet with moderate exercise are 

 desirable. 



Bronchitis. 



This affection is common in horses ; less so in dogs and' cattle. 

 It is characterized : By cotlgH; niofe or'less' fever (sometimes absent),
