![]() ![]() Lactic acid tests that indicate how successfully the blood is being distributed to the bodyīlood gas and oxygen saturation (SpO2) analyses to assess oxygenation statusĮlectrocardiogram (ECG or EKG) to monitor arrhythmias Routine bloodwork, including a complete blood count and biochemistry profile, to look for secondary issues and organ function All types of shock will require similar testing. Veterinarians may suspect shock based on a physical exam and the dog’s history. Survival after this stage of shock is rare. The late stage of shock, also known as late decompensated or irreversible shock, leads to systemic inflammation, systemic organ failure, and death. Without intervention and veterinary treatment, dogs will die once they have reached the intermediate stage. Often, this attempt reduces blood to the other organs, causing them to fail. In the intermediate stage, the body attempts to conserve blood volume and proper cardiac output by giving vital organs priority in blood distribution. This early stage can be difficult to recognize, but as time passes, shock can progress to an intermediate stage, known as early decompensated shock. In the early, or compensated, stage of shock, some animals only show mild clinical signs. The signs of shock continuously change and progress quickly. ![]() Seek emergency veterinary care immediately if you think your dog is showing signs of shock.Ĭheck your pet’s symptom Symptoms of Shock in Dogsĭogs in shock may have a history of trauma, surgery, weakness, collapse, vomiting, diarrhea, or decreased water intake.Īltered, dull mental state, such as lethargy or confusionĭehydration (presenting as decreased skin elasticity, tacky mucous membranes, sunken eyes) Shock in any form is a medical emergency. In other cases, one type of shock may lead to another as organs fail. For example, a dog in septic shock may also have a degree of hypovolemic shock. It is caused by abnormal cell metabolism and occurs in some cases of sepsis, low blood sugar, cyanide toxicity, pH abnormalities, and mitochondrial dysfunction.īecause of the complexity of shock, animals will often have multiple types of shock at the same time. Metabolic shock occurs when the tissues have good blood and oxygen supply but the cells can’t produce enough energy to stay alive. Examples of diseases leading to hypoxic shock include methemoglobinemia, carbon monoxide toxicity, severe lung disease, and anemia. This may be secondary to lung disease or to the blood’s inability to carry oxygen correctly. Hypoxic shock is caused by decreased blood oxygen levels. Systemic inflammatory response syndrome (SIRS), adverse drug reactions, drug overdose, heatstroke, and embolic disease are other causes of distributive shock. It is caused by a variety of abnormalities, generally associated with too much blood volume in the peripheral tissues and not enough circulating in the main vessels. This type of shock includes the more well-known subtypes: septic (due to infection of the bloodstream, commonly caused by bacterial infection) and anaphylactic (due to allergic response). It occurs due to heart disease, heartworm infection, toxins, drug reactions, or severe arrhythmias.ĭistributive shock, also known as vasodilatory shock, occurs when there is an incorrect distribution of blood flow. This happens with internal hemorrhage (ruptured tumors), external hemorrhage (trauma), coagulopathies (impairment of blood clotting ability), low blood protein, or dehydration (vomiting and diarrhea, burns, or decreased drinking).Ĭardiogenic shock is a severe form of heart failure, where the heart cannot properly pump blood throughout the body. Hypovolemic shock, the most common type, occurs when the circulating blood volume is dangerously low. In general, it is characterized by the following types and their causes: The term “shock” has different meanings, even among specialists. If your pet is not treated quickly, shock is usually fatal. Shock is a complex, whole-body reaction to various situations, typically caused by a lack of effective circulation, decreased oxygen, and/or decreased energy usage within cells. ![]()
