BOGS : THEIR MANAGEMENT. 



THE RECTUM. 



Piles. — The dog is very subject to these annoyances 

 in all their various forms ; for the posterior intestine of 

 the animal seems to he peculiarly susceptible of disease. 

 When enteritis exists the rectum never escapes, but is 

 Very frequently the seat of the most virulent malice of 

 the disorder. There are reasons why such should be the 

 case. The dog has but a small apology for what should 

 be a ccecum, and the colon I assume to be entirely want-

 the dog subsists, nevertheless a proportionate quantity of 

 its substance must be voided. If the excrement be less 

 than in beasts of herbivorous natures, yet there being 

 but one small receptacle in which it can be retained, the 

 effects upon that receptacle are more concentrated, and 

 the consequences therefore are very much more violent. 

 The dung of the horse and ox is naturally moist, and 

 only during disease is it ever in a contrary condition.

 which the rectum is exposed, even if the inclination to 

 swallow substances which itt their passage are likely to 

 cause excoriation did not exist. The grit, dirt, bone, and 

 filth that dogs will, spite of every precaution, manage to
