70 The Management and Diseases of the Dog. 



or two after feeding, especially if the dog had taken any 

 exercise." 



CALCULI IN THE STOMACH. 



These calculi are exceedingly rare in the dog. They 

 differ but little in appearance and character from those 

 found in other portions of the viscera, being chiefly com- 

 posed of the phosphates of lime and magnesia intermixed 

 with organic matter, and having a smooth glistening sur- 

 face. 



Medicinal treatment, particularly acids, would be more 

 likely to have a direct influence on them, by coming in 

 actual contact with them, than in renal or vesicular calculi. 



FOREIGN BODIES. 



The stomach of the dog is frequently the receptacle for 

 strange substances, some interesting cases of which are 

 recorded by Youatt. 



The presence of hair, straw, wood, stones, dung, and such 

 like, though usually found in rabies, are not to be taken 

 always as an infallible sign of that disease. 



The partaking of the latter (dung) is a frequent and dis- 

 gusting habit with young dogs, apparently in perfect 

 health. In unkennelled animals it is rarely seen, and 

 would therefore appear to a great extent to depend upon 

 the denial of sufficient liberty, and the contraction of 

 morbid tastes through confinement and injudicious manage- 

 ment. Hunger and filth play a prominent part in creating 

 such tastes.
