XXXII.— TUBERCULOSIS IN THE DOG. 



Among the canine patients received into hospital during the past 

 week two were entered as suffering from tuberculosis. Both were 

 suffering from pulmonary lesions, and were capable of spreading the 

 tuberculous poison throughout the places where they lived. 



I will recall the history of the first. This was a fine two-year-old 

 poodle, which was in the habit of accompanying its master each evening 

 to the tavern, where a prolonged stay was often made. About three 

 months ago this dog was noticed to leave portions of its food, to suffer 

 from cough, and to be wasting. It was unsuccessfully treated with 

 various tonic preparations. One morning, after having followed its 

 master, who was riding a bicycle, it returned home, lay down, and 

 refused food. Next day it still refused food, and would not leave its 

 kennel. The day after it was brought to the College. 



It was exceedingly dull and already much emaciated ; the temporal 

 muscles were wasted ; the respiration was rapid and discordant ; on 

 percussion the entire lower half of both sides of the chest was dull. 

 The chest was tapped on the right side, and a greyish turbid fluid 

 drawn off, in which bacteriological examination failed to discover 

 bacilli. But the thin bodily condition and the pleurisy left little doubt 

 regarding diagnosis : the dog was tuberculous. The owner consented 

 to leave it in hospital. The temperature was 39'8° C. (i03"6° F.), 

 nevertheless I injected lo centigrammes of tuberculin ; it produced a 

 reaction of three tenths of a degree C. ("5° P.). During the next two 

 days the temperature showed slight variations around 39"5° C. (103*1° 

 F.), the respiration steadily becoming quicker and more difficult. In 

 spite of a fresh tapping operation, in which more than one and three- 

 quarter pints of fluid were withdrawn, the condition continued to 

 grow more serious, and death resulted forty-eight hours later. 



We found no tuberculous lesion in the abdomen. The chest 

 cavity, however, still contained a certain quantity of greyish turbid 

 liquid holding in suspension opaque particles. The pleura was
