| Summary: | Background: The disease dioctophymatosis caused by the parasite Dioctophyma renale is a matter of veterinary public health, mainly in the control of zoonoses, monitoring of environmental pollution related to animals, hygiene and protection of animals. The Fish and frogs are paratenic hosts after ingestion of parasitized annelids. Humans and animals are definitive hosts after ingestion of intermediate or paratenic hosts with infective larvae. The objective was to describe a case of Canis lupus familiaris from a rural region, infested by a free adult D. renale in the abdominal cavity, indicating an alert for this zoonosis.

At laparotomy, a dark red cylindrical worm was seen immobile inside the abdominal cavity over the viscera, which was removed with the aid of anatomical tweezers, identified as a female Dioctophyma renale, 51 cm long. The abdominal cavity was visualized to check for further peritoneal and kidney damage. Based on the physical clinical examination and the results of the laboratory tests, it was decided to perform the initial elective surgical indication. The laparotomy suture was performed in the midline with 2-0 nylon thread, subcutaneous with 2-0 polyglactin thread, both with continuous sutures and the skin suture was with simple stitches separated with nylon. The postoperative protocol immediate consisted of analgesia and abdominal ultrasound was requested, which was not authorized by the tutor.
