Calculi in Bladder: 



Symptoms : In the dog the stones are generally 

 small, varying in size from a millet seed to a 

 pea, though occasionally one does find a large 

 one. In bitches the stone is generally not dis- 

 covered until it has become a good size, and set 

 up irritation of the bladder. In the dog, when 

 the stones are small they, as a rule, do not seem 

 to do any harm or cause inconvenience until one 

 or more escape from the bladder, pass into the 

 urinary passage or urethra, and become lodged 

 in the canal just behind the bone in the penis 

 where the passage is smallest. If the stone is 

 quite round — which, fortunately, is not always 

 the case — it acts like a cork in a bottle, and 

 the dog is unable to pass any water. He 

 stands or stoops like a bitch, and keeps strain- 

 ing ; but nothing comes away, except, perhaps, 

 a single drop occasionally of blood-stained urine. 

 If the stone happens to be not quite round, then 

 he is able to pass a small quantity of highly- 

 coloured water by great effort. To ascertain 

 for certain if these symptoms are the result of 

 gravel or stone, a small sound or catheter should 

 be passed ; and if there is any blockage in the 

 passage it is easily ascertained, for in that case 

 it will be impossible to pass the instrument for 

 more than a few inches instead of from 6 to 

 24 inches, according to the size of the dog ;
