The dog, like other animals, is liable to suffer from piles, causing it considerable discomfiture. The disease may be external, or internal. External piles consist of enlarged veins, the result of a sluggish circulation, and are more frequently seen in ladies' lap-dogs, or those leading an indolent and useless existence. Internal piles generally cause bleeding and pain during defecation, and are often seen protruding during the latter act.

Exercise, a liver laxative, such as 1 to 4 of Carter's Little Liver Pills now and then, with the application of a little gallic acid ointment, constitutes the safest treatment that the amateur can adopt.
