72 THE MANAGEMENT AND DISEASES OF THE DOG. 



Diet. — The same rules regarding the diet in diarrhoea will 

 apply in dysentery, and warmth, cleanliness, and dryness are 

 equally essential 



INTUS-SUSCEPTION. 



This intestinal condition is commonly met with in the dog. 

 When one portion of the tube " telescopes " or becomes in- 

 vaginated within the portion anterior or posterior to it, what 

 is termed intus-susception is established. 



The small intestines are those generally involved. 



Intus-susception usually terminates fatally ; adhesion, how- 

 ever, of the invaginated portion may take place, followed by 

 suppuration and separation of that part. 



In a re.cent post-mortem examination of a large mastiff dog, 

 I found death had resulted from stoppage and consequent in- 

 flammation, owing to constriction of the bowel immediately 

 in front of an old intus-suscepted portion, in which adhesion 

 was established, but the process of separation had not become 

 complete. 



In a still more recent one, of a fox-hound, I found acute 

 inflammation of the bowel at and anterior and posterior to an 

 invaginated portion of seven inches in length, in which adhe- 

 sion had not commenced. 



The following case was recorded by Jonathan Hutchinson, 

 in 1876: 



Intus-susception of the Ileum and Caecum in a Dog. 



This specimen was taken from a dog about ten months old. 

 The ileum and caecum had passed into the colon for a distance 

 of about eight inches, until the caecum nearly presented at 

 the anus. The layers, were not in the least adherent, and it 

 might have been reduced by traction from within the abdo- 

 men with great ease. Although the impacted parts were 

 much congested, there was no tendency to gangrene, nor any
