How do you calculate maintenance fluid rate and factor dehydration and ongoing losses for a 5 kg dog?

• A. Maintenance ~60 mL/kg/day (~2.5 mL/kg/hour). Add deficit for percent dehydration (weight × %dehydration) and add ongoing losses (vomiting/diarrhea). Use balanced crystalloids and monitor clinically.
• B. Maintenance 5 mL/kg/day; ignore dehydration.
• C. Maintenance 200 mL/kg/day; multiply by weight for daily.
• D. Maintenance is 100 mL/kg/day plus dehydration.

Answer: (D)
