j6 The Management and Diseases of the Dog. 



two days before his death he was intensely jaundiced. In 

 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 Societfs Trans- 

 actions. 



Symptoms.— Th.ere are no special diagnostic symptoms of 

 intus-siisception 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. It is, perhaps, hardly neces- 

 sary to observe that their presence causes their host much 

 annoyance, and is frequently productive of disease. 



Vomiting, pasalysis, irectal irritation — denoted by the ani- 

 mal frequently licking the part, and dragginghimself along in 

 a sitting posture — purging, inordinate appetite, enlarged ab- 

 domen, harsh,staringcoat, emaciation, and more or less febrile 

 disturbance, are among the symptoms usually presented 

 in such cases, while ocular demonstration of the fact is not 

 frequently wanting.

 ment, see chapter on " Internal Parasites."
