A dog weighing 10 kg requires approximately how many milliliters for its IV shock dose?

• A. 600 ml
• B. 800 ml
• C. 1000 ml
• D. 1200 ml

Answer: (B)

In emergency resuscitation for a dog in shock, the aim is rapid intravascular volume expansion using isotonic crystalloids, delivered as a series of small boluses until perfusion improves. A common shock dose is about 80 mL per kilogram of body weight, given as IV boluses (often 20 mL/kg at a time and reassessed after each dose, up to four boluses to reach roughly 80 mL/kg). For a 10 kg dog, that calculates to 80 mL/kg × 10 kg = 800 mL. So the approximate shock dose is 800 mL. (Some guidelines cite up to about 90 mL/kg, which would be around 900 mL, but 800 mL reflects the typical exam standard.)
