48 INFLUENZA* 



The expression of the eyes is changed in a marked degree, wearing a 

 depressed anxious look. Late in the disease there is a tendency to dropsy 

 of the lmihs, and sometimes an effusion into the chest. 



Diagnosis. —To distinguish between other affections resembling influ- 

 enza should not be difficult; the existence of an epidemic, other dogs 

 being attacked at the same time; the great prostration from the first; the 

 fever of a remittent type ; the peculiar cough and absence of signs indica- 

 tive of disease of the lungs. A consideration of these facts should make 

 a differential and positive diagnosis easy. 



Prognosis. — If uncomplicated, the disease commonly ends in recovery. 

 In old dogs and in very young puppies it runs a more severe course. The 

 existence of other diseases, and a weakened and impoverished system 

 would render a prognosis more unfavorable. 



Treatment. — The animal should be placed in a room of even tempera- 

 ture and well ventilated, but free from draughts. In mild cases the 

 medicinal treatment need not be especially active. The congestion of the 

 head can be relieved by gentle laxatives, but purgatives are contra-indica- 

 ted. If the fever runs very high, quinine in three grain doses should be 

 given every four or five hours. "When the temperature has become normal 

 the quinine may be continued in two grain doses, twice or three times 

 daily for a time. If the laryngeal inflammation is severe, hot applications 

 should be made to the neck, or the same rubbed well with the ammonia 

 and camphor liniments in equal parts, and afterwards swathed in cotton 

 or flannel. 



In extremely severe cases where the breathing becomes difficult, the 

 animal may be made to inhale steam ; the water from which it is generated 

 should be tinctured with carbolic acid, two drachms to the pint. An admi- 

 rable method of keeping the air the animal breathes constantly disinfected, 

 is to use some form of lime and carbolic acid mixed together. 



An important consideration in treatment is to guard against possible 

 failure of the vital powers, especially in old dogs and others weakened 

 by diseases. Quinine or iron should be persisted in, and the following 

 mixture be given.—

 The diet should be easily digestible ; milk, broths, and if needed, eggs 

 added to the former. 



During the convalescent stage, the animal should be judiciously exer- 

 cised in the bpeu air, but guarded against exposure,
