Emphysema] * ^3 [Emphysema 



through a small puncture in the skin, which 

 often cannot be found when a dog's coat is 

 thick. The emphysema may be confined to the 

 body or to the head, or even to one or more 

 limbs. In bad cases the dog swells out of all 

 recognition. He is unable to move, or does 

 so with great difficulty ; and when the head is 

 affected, the eyes are closed, the ears perhaps 

 an inch thick, and breathing is difficult. The 

 swelling is soft, pits on pressure, and at the 

 same time a crackling noise is made. 



When affecting the lungs, the breathing is 

 heavy and laboured, and on auscultating the 

 chest a distinct loud, crackling noise is heard. 

 The heart is generally affected, its action, as 

 a rule, being very weak ; and there is a 

 chronic, husky cough. 



Treatment: In cases of general emphysema, 

 if the swelling is not large it may be left alone, 

 for it will gradually disperse of its own accord ; 

 but when it is large, the original wound, if it can 

 be found, should be dilated, or one or more fresh 

 ones made, and the air which has accumulated 

 under the skin pressed out. The wound should 

 afterwards be cleaned with a solution of some 

 disinfectant like Pearson's fluid or boracic acid, 

 dried, then covered over with some antiseptic 

 gauze, and a bandage or coat applied. 

 Stimulants, as brandy, should be administered. 

 Treatment of emphysema of the lung is not 

 very satisfactory, especially when the patient is 

 very old, which is generally the case ; but some 

 relief may often be given by careful dieting. No
