CATARRHAL ENTERITIS IN DOGS. 



Causes : faulty feeding, close confinement, youth, distemper, overexer- 

 tion, meat diet, chills when heated and fatigued, ferments, bacteria, debility, 

 ill-health. Lesions : congested, softened, ulcerated, thickened mucosa, 

 mucopurulent exudate, swollen intestinal and mesenteric glands, hyper- 

 plasia, polypi, follicular degeneration. Symptoms : dullness, segregation, 

 inappetence, fever, arched back, abdominal rumbling, tenderness, retraction, 

 constipation, diarrhoea, colics, vomiting, tenesmus, swollen red excoriated 

 anus, icterus, weakness, debility, paralysis, if chronic, unthrifty skin, with 

 eruptions, pallor, foul breath, tongue and gums, emaciation. Course : may 

 recover in vigorous, or run down and die in old, young, weak, debilitated 

 or ill. Relapses. Treatment: dietetic, laxative, in icteric, calomel, manna, 

 enemata, warm bath, synapism, antiseptics, bismuth, sodium salicylate, in 

 diarrhoea, bitters, astringent antiseptic tonics. Demulcents. 



Causes. The dog is susceptible because of its varied, irregular, 

 stimulating, often exces.sive diet, and its close confinement and 

 lack of wholesome outdoor exercise. The conditions which pre- 

 dispoise to or excite gastritis tend equally to enteritis. Youth, 

 canine distemper, overexertion, an exclusive meat diet, and chills 

 from plunging into cold water when exhausted with hunting are 

 to be specially noted. Spoiled meats charged with the germs of 

 infection, or with putrefactive bacteria and their toxic products 

 are common causes. Then any old standing disease or other 

 cause of general debility will predispose to the attacks of such 

 otherwise harmless germs. The irritation caused by intestinal 

 parasites is an occasional factor. 



Lesions. The mucosa is congested, ramified, spotted or dark 

 and slaty ; it together with the submucosa is swollen and infil- 

 trated, and with points of ecchymosis, extravasation or eve 

 ulceration. The surface has a thick layer of mucopurulent 

 matter. The solitary glands are swollen and charged with small 

 lymphoid or pus cells and have a congested areola. The mesen- 

 teric glands are congested and the liver usually congested 

 softened or mottled. In chronic cases there may be hyper- 

 pla.sia, polypi, cystoid degeneration of the follicles, etc. 



Symptoms. There may be dullness, drowsiness, a seeking of 

 seclusion, inappetence, hyperthermia (102 to 104°) ardent thirst, 

 arched back, abdominal rumbling, tympany or tucked up tender
