76 The Management and Diseases of the Dog. 
two days before his death he was intensely jaundiced. Ia 
reference to the non-occurrence of adhesions between the 
layers of impacted intestine, it must be borne in mind that 
experiments have established the fact that dogs are but 
little prone to peritonitis.— Pathological Societys Trans- 
actions. 
Symptoms.—There are no special diagnostic symptoms of 
intus-susception in the dog. Those of colic are generally 
at the onset present, and are succeeded by enteritic ones. 
Frequent violent straining and vomiting are also invariably 
present. But the same may occur in strangulated hernia, 
and other intestinal affections. 
Treatment.—A large dose of linseed or salad oil should 
first be administered for the purpose of mechanically facili- 
tating the return of the invaginated portion, or inflation of 
the bowels with air might be adopted with good results, or 
the administration of quicksilver could be tried. The suc- 
ceeding treatment should be as for colic and enteritis, or 
both combined. 
WORMS. 
Dogs are invariably, during some portion of their lives, 
troubled’ with worms, and the most common seat of these . 
pests is in the intestinal canal. Itis, perhaps, hardly neces- 
sary to observe that their presence causes their host much 
annoyance, and is frequently productive of disease. 
Vomiting, paralysis, rectal irritation—denoted by the ani-. 
mal frequently licking the part, and dragging himself along ia 
a sitting posture—purging, inordinate appetite, enlarged ab- 
domen, harsh, staring coat, emaciation,and more orless febrile 
‘disturbance, are among the symptoms usually presented 
in such cases, while ocular demonstration of the fact is not 
frequently wanting.
