Summary Splenic abscesses are exceedingly rare in dogs, with few descriptions in the veterinary literature. This report describes a 10‐year‐old, spayed, female Australian shepherd dog mix that developed a splenic abscess following septic peritonitis secondary to a jejunal perforation. The dog initially underwent surgical correction of the jejunal perforation and recovered well, but presented 16 days later with recurrent fever and lethargy. Repeat ultrasonography identified a splenic lesion, and exploratory surgery revealed an abscessed, infarcted spleen requiring splenectomy. Histopathology and culture confirmed splenic abscess without evidence of neoplasia. The patient recovered fully following antimicrobial therapy and postoperative monitoring. To the authors’ knowledge, this is the first reported canine case of splenic abscess formation secondary to postoperative abdominal sepsis. This case highlights the importance of considering delayed septic sequelae in patients with previous septic peritonitis and demonstrates that timely surgical management can result in an excellent outcome.
