The symptoms of severe peritonitis in dogs include:

Dog owners need to be aware of the symptoms of severe peritonitis in their pets, as early detection can be crucial for the dog's survival and recovery. Peritonitis is an inflammation of the peritoneum, the lining of the abdominal cavity, and it can be caused by a variety of factors such as infection, trauma, or a rupture in the abdominal organs.

One of the primary symptoms of severe peritonitis is a noticeable change in the dog's behavior and activity level. Dogs may become lethargic and show a lack of interest in playing or going for walks. They might also appear restless and unable to find a comfortable position to lie down. This change in behavior is often accompanied by a decrease in appetite and weight loss.

Abdominal pain is another key indicator of peritonitis. Dogs may exhibit signs of discomfort by whining, growling when touched, or trying to bite if their abdomen is pressed. The abdomen may feel tense and rigid to the touch, and the dog might stand with an arched back to alleviate the pain.

Vomiting and diarrhea are common gastrointestinal symptoms associated with severe peritonitis. Vomiting can be projectile and persistent, and it may contain blood. Diarrhea can also be severe and may also have blood in it. These symptoms can quickly lead to dehydration and electrolyte imbalances, which can be life-threatening if not addressed promptly.

Another symptom to watch for is fever. Dogs with peritonitis often have an elevated body temperature. This may be accompanied by signs of lethargy and a general feeling of being unwell. You can check your dog's temperature with a rectal thermometer, but if you suspect peritonitis, it's best to have a veterinarian do this.

Difficulty breathing can also occur due to the pain and the stress of the condition. Dogs may take shallow breaths or breathe rapidly. This can be particularly distressing for the pet and may require immediate veterinary attention.

If you suspect your dog has severe peritonitis, it's important to seek veterinary care immediately. Treatment for peritonitis typically involves hospitalization, intravenous fluids to combat dehydration, and antibiotics to fight infection. In some cases, surgery may be necessary to repair the underlying cause of the inflammation, such as a ruptured organ or foreign body.

While at the vet, the dog may undergo various tests, including blood work, abdominal X-rays, and an ultrasound to determine the cause and extent of the peritonitis. The vet will also monitor the dog's vital signs and provide pain management as needed.

To help prevent peritonitis, it's essential to keep your dog healthy and watchful of their environment. This includes maintaining a proper diet, ensuring they don't ingest foreign objects, and keeping them safe from trauma. Regular veterinary check-ups can also help detect any issues early on.

Being vigilant about your dog's health and recognizing the symptoms of severe peritonitis can make a significant difference in their prognosis. Early treatment is essential for a successful recovery, so any changes in behavior, appetite, or appearance should prompt a visit to the vet. Remember, prompt action can save your dog's life.
