164 THE DISEASES OF THE DOG. 



exploration of the parts and retraction of the prepuce to 

 expose the glans is a matter of some difficulty. In neglected 

 cases ulcers form about the parts and a loathsome state 

 of disorganisation ensues, the pus sometimes burrowing 

 along the side of the penis and bursting out at intervals. 

 Treatment comprises thorough examination, after cleansing 

 the parts and retracting the prepuce when necessary ; 

 cutting off the long hairs about the orifice ; fomenta- 

 tions to allay inflammation and pain ; followed by astrin- 

 gent lotions. Tonics and demulcents should be given 

 internally after the bowels have been cleared out by a 

 cathartic. Spasm and stricture of the urethra seldom occur 

 in the dog. 



A Parasite in the Urethra caused obstruction to 

 the passage of urine and severe urethral irritation. At 

 length it protruded through the meatus, and its removal 

 with the forceps gave the animal immediate relief. M. 

 Seon, who reports the case, found the worm four inches 

 and a half long, and considered it a strongylus ; possibly 

 it was a male Str. gigas ?* 



Urethral Calculus is generally a small cystic stone 

 impacted in its passage. Manipulation may enable us to 

 bring it down to the orifice of the canal and there grasp 

 it with the forceps and so afford relief, otherwise an 

 incision must be made on it, where it can be felt in the 

 urethra, and removal so effected. When in the intrapelvic 

 portion of the canal it may be detectable only on passing 

 the catheter ; there too it must be cut down upon for 

 removal should the natural efforts not suffice to move it 

 onwards and if it remain fixed even after the adminis- 

 tration of chloroform and opium.
