7o 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 toa 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.
