Total blood volume in most non-feline domestic animals is approximately what percent of body weight?

• A. 5%
• B. 7%
• C. 10%
• D. 15%

Answer: (B)

Blood volume is normally about seven percent of body weight in most non-feline domestic animals. This baseline is what clinicians use to estimate how much blood an animal has and to guide decisions about transfusions or fluid therapy. For example, a 10 kg dog would have roughly 700 mL of blood (10 kg × 70 mL/kg). The other percentages would represent either a lower or higher baseline than is typical (5% ≈ 50 mL/kg, 10% ≈ 100 mL/kg, 15% ≈ 150 mL/kg), which is why seven percent is the standard reference.
