PILES— FISTUL.E IN THE ANUS. 165 



PILES. 



Dogs are very subject to piles, but the symptoms by which the 

 complaint shews itself are by no means known as such, although 

 they are not very dissimilar to the human haemorrhoids. The 

 complaint is brought on by confinement, heat, and heating food ; 

 and shews itself by a sore red protruded anus, which the dog ag-

 is considerable, give daily one of the following powders : — 



Nitrated po". ash ('weVrgj, powdered. .. . half a drachm 

 Milk of sulphm- 3 drachms 



Divide into nine, twelve, or fifteen doses. 



FISTULA IN THE ANUS.

 mation of faeces so hard, and so difficult of evacuation as often to 

 abrade the rectum, and produce inflammation and ulceration : this 

 sometimes has ended in leaving a fistulous opening in the cellular 

 substance which surrounds it, and which usually makes its way
