Final answer:
The primary therapy for treating hypovolemic shock in canines is to restore circulating blood volume, typically through intravenous fluids and possibly with the addition of blood pressure raising medications if necessary.
Step-by-step explanation:
In treating hypovolemic shock in the canine, the most important form of therapy is to c) Restore circulating blood volume. Hypovolemic shock is a condition that arises due to significant fluid loss, such as from hemorrhage, severe vomiting, diarrhea, or extensive burns. Restoring blood volume is typically achieved by providing intravenous fluids to replenish lost volume and maintain sufficient oxygen and nutrient supply to tissues. In severe cases, various drugs such as dopamine, epinephrine, and norepinephrine may also be administered to raise blood pressure and support circulatory function.
