74 The Management and Diseases of the Dog. 
Causes —Protracted and severe diarrhoea, putrid and un- 
wholesome food, vitiated bile, intense heat, and foul smells. 
Symptoms.—Dysentery may be ushered in with rigors, 
general febrile excitement, and offensive evacuation ; or be 
preceded by flatulency, constipation, colicky pains, nausea, 
and vomiting. The anal discharge varies in appearance ; 
sometimes it resembles pure mucus, at others blood mixed 
with mucus, while, not unfrequently, pure blood is voided. 
As the disease proceeds, and ulceration is developed, pus 
becomes mingled with the discharge, as well as membranous 
shred-like particles (the latter an ominous sign). Con- 
siderable prostration is attendant throughout ; the pulse is 
weak and quick, the respiration increased, the eyes sunken, 
mucous membranes injected, the nose dry and hot, mouth 
slimy and breath offensive; with these there is loss of 
appetite, considerable thirst, and disinclination during the 
latter stages to move, the evacuations being involuntary 
and most disgusting. 
Treatment—-The medicinal treatment of dysentery 
should be essentially anodyne and astringent. The sul- 
phate of copper and opium stand pre-eminent, and may 
be given in the proportions named in the foregoing disease, 
three or if necessary four times per day. I am no advocate 
for blond-letting in this excessively reducing malady. As 
a local application I prefer a hot linseed-meal poultice to 
the abdomen. When the discharge is excessive, and 
mingled with blood, a tablespoonful of starch, with 10 drops 
of laudanum, may be injected, or 20 drops of tinct. ferri in 
a tablespoonful of iced water, and repeated if necessary. 
Diet—The same rules regarding the diet in diarrhoea 
will apply in dysentery, and warmth, cleanliness, and dry- 
ness are equally essential. 
INTUS-SUSCEPTION. 
This intestinal condition is commonly met with in the dog. 
When one portion o1 the tube “ telescopes” or becomes in-
