DISEASES OF THE URINARY SYSTEM. 277 



In the male dog reacliiiig the bladder in this way is 

 not easy ; a small gum-elastic catheter will be required. 

 The dog should be laid on his side, the instrument warmed 

 in hot water and well oiled, gently passed in till its point 

 can be felt with one finger in the rectum, when it may be 

 guided onward into the bladder. 



This operation is to be avoided if possible, as it is 

 neither easy to the manipulator nor agreeable to the dog ; 

 and if there be much struggling, harm may follow the 

 attempt. 



In extreme cases ether may be given, and, if the cathe- 

 ter can not be passed, an opening made into the bladder to 

 save life ; otherwise rupture of the bladder and inflamma- 

 tion following this, if not sudden death, or urgemic poison- 

 ing result from retention of the material in the blood 

 which the kidneys should remove ; but it is seldom in- 

 deed that the treatment with opiates or the hot bath will 

 not suffice. 



Suppositories in the above and other painful affections 

 of this region will be of great service if they can be re- 

 tained in the rectum. 



As an example of a suitable combination we offer the 

 following : 



'^ Pulv. opii gr. vj ; 



Ext. belladon gi"- iij ; 



Oh theobrom 3ij. 



M Ft. suppos. no. vi. Use one every two to six 

 hours, as needed to relieve pain. 



Hot injections by the rectum of warm water medicated 

 with laudanum or belladonna often prove very useful. 



The dog may suffer from inflammation of the kidney
