PILES. ...POISONS. 211 



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. Piles are broug-ht on by confinement, heat, and 

 heating- food ; and shew themselves by a sore red protruded 

 anus, which the dog* aggravates by dragging it on the floor. 

 Piles are likewise frequently the effect of costiveness. The 

 tenesmus occasioned by diarrhoea may readily be mistaken 

 for piles, from the anus appearing red and sore. In such a 

 case, to effect a cure the looseness must be restrained, and 

 the sore anus may be anointed with the ointment directed be- 

 low, omitting the tar. 



The habitual piles will be greatly relieved by the use of the 

 following ointment: — 



Sugar of lead 6 grains 



Tar half a dram 



Elder ointment, or fine lard 3 drams. 



Mix, and anoint the fundament with it two or three times 

 a-day. To correct the habit towards the disease, feed mo- 

 derately on cooling food, exercise sufficiently, and, as long 

 as the disposition to it is considerable, give daily one of the 

 following powders : — 



Nitrated potash (nifre), powdered half a dram 



Milk of sulphur 3 drams. 



Divide into nine, twelve, or fifteen doses.
