Septic Shock in Dogs

Septic shock is the result of a widespread infection in dogs.

Septic shock is the end stage of sepsis in dogs. Sepsis is a widespread, systemic inflammatory response to an infection.

During septic shock, circulatory collapse leads to life-threatening heart, respiratory, and organ failure.

Causes and Course of Septic Shock in Dogs

Septic shock occurs as a result of sepsis, which is a widespread, systemic infection. A bacterial infection is the most common cause of sepsis and, later, septic shock.

Septic shock occurs when there is so much toxin circulating in the bloodstream from an infection, along with inflammatory cells from the immune system, that the circulatory system is overwhelmed and collapses. That leads to multi-organ failure.

The causes of sepsis and, subsequently, septic shock in dogs can include:

Signs of Septic Shock in Dogs

When a dog is experiencing septic shock, the signs progress or cascade.

During early septic shock, signs include:

During late septic shock, as the body is losing the ability to deal with the situation, signs include the above and also:

Additional signs related to the primary condition that caused the sepsis may also be present.

Diagnosis of Septic Shock in Dogs

A complete blood count (CBC) done on a dog with sepsis will show increased white blood cell counts and possibly signs of toxicity in those cells. Indications of dehydration may also be present in the CBC. Low platelet levels are also commonly seen during this condition.

Clotting values will be abnormal if DIC has been triggered.

Low blood albumin (protein) levels may be present during septic shock, and there will likely be high liver and kidney values.

X-rays, ultrasound, bodily fluid analysis, urinalysis, and other testing may help diagnose the underlying cause of the sepsis.

Treatment of Septic Shock in Dogs

Septic shock is an emergency, life-threatening condition that must be treated in a veterinary hospital. The following treatments may be necessary:

Once septic shock has set in, it carries a poor prognosis. Up to 65% of dogs with septic shock will die. Aggressive veterinary treatment as soon as possible gives a dog the best chance to recover.
