A 3-year-old male mixed-breed dog from Termas de Río Hondo, Argentina, presented with a one-month history of gastrointestinal signs, including hemorrhagic diarrhea, vomiting, abdominal pain, and initial fever, which were refractory to treatment. Upon admission to the veterinary service, the patient showed 7% dehydration. Ultrasonographic examination revealed duodenal wall thickening and jejunal lymphadenomegaly. Exploratory laparotomy confirmed severe intestinal lesions, and an enterectomy was performed with sample collection for histopathological examination, along with blood transfusion. Forty-eight hours after surgery, the patient developed ascites with a positive culture for Proteus mirabilis. Histopathology confirmed lesions compatible with enteric pythiosis caused by Pythium sp. The patient died within the next 24 hours. This case highlights the aggressiveness of enteric pythiosis and the importance of early diagnosis in endemic areas. Paciente canino mestizo, macho, de 3 años, procedente de Termas de Río Hondo (Argentina), presentó signos gastrointestinales con un mes de evolución (diarrea hemorrágica, vómitos, dolor abdominal y fiebre inicial), refractarios al tratamiento. Al ingresar al servicio veterinario presentaba una deshidratación del 7%. Ecográficamente se reveló engrosamiento duodenal y linfadenomegalia yeyunal. La laparotomía exploratoria confirmó lesiones intestinales graves, realizándose enterectomía con toma de muestra para histopatología y transfusión sanguínea. A las 48 horas posquirúrgicas desarrolló ascitis con cultivo positivo a Proteus mirabilis. La histopatología confirmó lesiones compatibles con pitiosis entérica por Pythium sp. El paciente falleció en las 24 horas posteriores. Este caso resalta la agresividad de la pitiosis entérica y la importancia del diagnóstico temprano en zonas endémicas.
