HEMORRHAGIC GASTRO-ENTERITIS OF THE DOG. 



Definition. Causes : Spring, toxins, irritants, inflammation. Symptoms : 

 Vomiting, diarrhoea, pendent head, arched back, retracted belly, black, 

 bloody glairy frothing fasces, circulation excited, mucosas red, yellow, or 

 brown, death in two or three days. Diagnosis. Lesions : Stomach and 

 intestines empty, mucosa of a dark blood red, thickened, liver and kidneys 

 congested. Treatment : Little successful, intestinal disinfection, elimina- 

 tior, laxatives, wet compresses, enemata, heart stimulants, ergot, iron 

 chloride.
