Canine Septic Peritonitis in Dogs: what real veterinary cases show
Canine septic peritonitis is a serious and potentially life-threatening condition that occurs when the peritoneal cavity, the space within the abdomen, becomes infected with bacteria. This condition often results from a rupture in the gastrointestinal tract, but it can also occur due to trauma, surgical complications, or the spread of infection from other areas of the body.
Dogs with septic peritonitis may exhibit symptoms such as abdominal pain, fever, vomiting, and lethargy. Prompt veterinary attention is crucial, as the condition can rapidly progress to septic shock, a critical state that requires immediate intervention. Treatment typically involves surgical intervention to address the source of infection and intensive supportive care to stabilize the patient.
What vets typically check for
- Perform a thorough physical examination and obtain a detailed history.
- Conduct abdominal imaging (ultrasound or X-rays) to identify fluid accumulation or source of infection.
- Analyze abdominal fluid through cytology and culture to confirm bacterial infection.
- Initiate broad-spectrum antibiotics and fluid therapy to stabilize the patient.
- Consider surgical intervention to repair any ruptures or remove infected tissue.

- Clinical and pathological aspects of gossypiboma in a dog: case report
Arquivo Brasileiro de Medicina Veterinária e Zootecnia · BR
A female dog was brought to the emergency vet with a swollen belly, pain, and significant weight loss. An ultrasound revealed a mass inside her abdomen that couldn’t be clearly identified. The vet performed surgery to explore the area, but unfortunately, the dog passed away after the operation. The cause was found to be a gossypiboma, which is a serious condition caused by left
- Erythrocyte Sedimentation Rate as a Monitoring Marker in the Canine Intensive Care Unit.
Journal of veterinary emergency and critical care (San Antonio, Tex. : 2001) · 2026 · Italy
A group of 124 dogs in the intensive care unit (ICU) had their erythrocyte sedimentation rate (ESR) tested to see if it could predict their chances of survival. The results showed that dogs who did not survive had a much higher ESR at admission compared to those who did survive. Additionally, the ESR levels changed differently over time: survivors had a decrease in ESR, while n
- Absence of an elevated temperature at admission is not associated with mortality in dogs with septic peritonitis.
Journal of the American Veterinary Medical Association · 2026
A group of 60 dogs diagnosed with septic peritonitis (a serious abdominal infection) was evaluated to see if their body temperature at admission affected their chances of survival. Surprisingly, 37 dogs had normal temperatures, and 49 of the 60 dogs survived after treatment, regardless of their temperature when they arrived. The study found that temperature did not influence ho
- Hemorrhage is associated with decreased prognosis compared to all other indications for unplanned recurrent celiotomy.
Journal of the American Veterinary Medical Association · 2026
A dog that had surgery for a stomach issue needed a second surgery within two weeks due to complications. The most common reasons for the second surgery were severe abdominal infections and bleeding. Unfortunately, bleeding was linked to a much lower chance of survival, with many dogs not making it home after treatment. The study highlights the importance of monitoring for comp
- Vacuum-assisted closure as a component of the management of deep surgery site infection after canine cementless total hip replacement.
Australian veterinary journal · 2026 · Australia
A dog that had a total hip replacement developed a serious infection at the surgery site. To treat this deep infection, veterinarians used a vacuum-assisted closure (VAC) system, which helps promote healing by drawing out fluids and keeping the area clean. This method proved effective, leading to a successful recovery for the dog. The VAC technique is also commonly used in huma
- A Case of Sepsis Caused by ST80 Multidrug-Resistant Enterococcus faecium With Concurrent Klebsiella pneumoniae Infection in a Dog.
Veterinary medicine and science · 2026 · South Korea
An 8-year-old mixed-breed dog was brought to the vet with severe breathing problems, coughing up blood, and signs of serious illness. Unfortunately, the dog was diagnosed with a severe infection caused by a drug-resistant bacteria called Enterococcus faecium, which led to sepsis (a life-threatening response to infection). Despite testing for various infections and trying differ
