42 The Management and Diseases of the Dog. 



preceded it, and we may tap again with the same result. 

 There are, nevertheless, exceptional cases : m the horse I 

 have seen recovery follow the operation, and also in the dog. 



CHRONIC PLEURISY 



May, as I have stated, be a termination of the former, or 

 it may begin as a chronic affection, i.e., it may assume a 

 sub-acute form from the commencement. Pain on the 

 affected side, cough, increased pulse, and respiration con- 

 siderably accelerated by exertion, and more or less fever, are 

 the symptoms generally present. Effusion, or lymph and 

 adhesions are usually present ; as the lymph becomes or- 

 ganized, the fluid absorbed, and the adhesions firmer, the 

 walls of the chest become flattened ; dulness on percussion, 

 feebleness of the respiratory murmur, and an occasional 

 rasping sound attend this condition. 



Treatment. — This consists in endeavouring to promote 

 absorption of the effused fluids, and in giving strength to the 

 patient. The sulphate of iron, in from 5 to 15 grains, in pro- 

 portion to the size of the animal, with cod-liver oil, forms 

 the best and, I have found, the most successful medicinal 

 treatment.- 



Mild continued counter-irritation to the sides of the chest 

 is also advisable. The application of the tincture of iodine, 

 after first shaving off the hair, is exceedingly useful, and the 

 insertion of a seton in front of the chest for a month or six 

 weeks is most valuable. 



The diet should be nourishing, and every means adopted 

 which is calculated to impart vigour. 



PNEUMONIA, 



Or inflammation of the substance of the lungs, is a complaint 

 to which dogs are exceedingly liable.
