DOG. PI^EURISY. 



Causes, exposure to cold, etc. Chill, reaction, disturbed breathing, 

 catching inspiration, rapid, hard pulse, hyperthermia, tender chest, friction 

 sound, later dullness at lower part of the chest in any position. Treatment, 

 as in pneumonia, with antirheumatics and diuretics freely. Thoracentesis. 



This is occasionally seen in the dog as the result of exposure, 

 and like other diseases of the chest is easily recognized. It owns 

 the same causes with pneumonia. 



Symptoms. There is first dulness, shivering and some excite- 

 ment of respiration. To this follow the more acute symptoms, 

 the hard pulse, the rapid, catching breathing, the animal standing 

 or sitting on his haunches, the open mouth, pendent tongue, the 

 injected mucous membrane, the costiveness, but above all the 

 tenderness of the intercostal spaces, the early friction sound on 

 auscultation, the pain and normal resonance on percussion, the 

 muscular twitchings and the short, suppressed, painful cough. 

 When effusion has occurred its amount may easily be estimated 

 by turning the animal alternately on its feet, back and haunches, 

 and observing how high the dullness extends in these various 

 positions. 



The same treatment may be adopted as in pneumonia, with this 

 difference that salicin may be given freely, and when effusion has 

 taken place active diuretics are specially indicated, and hence 

 tincture of squils (a teaspoonful) may be made to replace the 

 nitre. In advanced and obstinate cases, or where danger exists 

 from rapid effusion, the liquid may be drawn off with a cannula 

 and trochar as in other animals.
