Pseiido-Membraiious {Cro7ipous) Enteritis in Dogs. 225 



attributed it to too rich milk, and exposure to cold draughts, in 

 folded lambs. 



Symptoms. To the general symptoms of fever are added 

 refusal of the teat, weakness or paresis of the hind limbs, loose- 

 ness of the bowels and the ejection of false membranes with an 

 unusual amount of straining. The dejections may be watery and 

 mixed with blood. In some cases defecation is suppressed, the 

 intestines being blocked by the membranes, and then acute indi- 

 gestion and fatal tympany may follow. 



The pathological anatomy and lesions resemble those seen in 

 the ox. 



Treatment. Change the diet of the ewe, and allow more out- 

 door exercise. Give the lamb Glauber salts (3^4 to i oz.) with 

 potassium iodide (logrs.), and bismuth (i dr.). Decoctions of 

 flax-seed, or solutions of elm-bark, mallow or gum arable are 

 desirable, and infusions of aromatic plants or oils of peppermint, 

 anise, or fennel may be added with quinia. As in the other ani- 

 mals such antiseptics as salol, napthol, naphthalin, boric acid, or 

 salicylate of soda mav be administered. 



PSEUDO-MEMBRANOUS (CROUPOUS) ENTERITIS IN 



DOGS. 



Complication of other diseases like distemper. Symptoms : fever, retch- 

 ing, vomiting, tense, tender, tympanitic abdomen, irregular bowels, false 

 membranes. Lesions : stomach empty, congested, croupous exudate, ex- 

 travasations. Treatment : sodium sulphate, boric acid, sodium salicylate, 

 salol, bismuth, hy mouth or enema, strychnia, vermifuges. 



In dogs the formation of false membranes on the intestinal 

 mucosa seems to have less of an individual character, and is 

 found associated with other affections, like canine distemper and 

 parasitism. In the absence, however, of accurate knowledge of 

 the specific cause of croupous enteritis in other animals it seems 

 permissible for the present, to arrange the whole in one class 

 characterized by the presence of false membranes. 



Symptoms. Along with the general symptoms of fever and the
