Dog Potassium Supplementation Calculator
Calculate the appropriate potassium supplementation rate for hypokalaemic dogs — with safe maximum infusion rate guidance.
What Is the Dog Potassium Supplementation Calculator?
Calculate the appropriate potassium supplementation rate for hypokalaemic dogs — with safe maximum infusion rate guidance.
Hypokalaemia causes muscle weakness, ileus, and cardiac arrhythmias. This calculator determines the appropriate potassium chloride supplementation rate based on serum potassium level and fluid rate.
Every result is based on published veterinary research and breed-size-specific growth data — not generic averages. This tool is completely free, works instantly in your browser, and requires no account or sign-up.
How to Use This Calculator

How It Works
Potassium supplementation is guided by the Haskins scale — the potassium concentration added to IV fluids depends on the severity of hypokalaemia. Below 2.0 mEq/L: 80 mEq/L. 2.0-2.5: 60 mEq/L. 2.5-3.0: 40 mEq/L. 3.0-3.5: 28 mEq/L. Above 3.5: 20 mEq/L maintenance. The maximum safe IV potassium delivery rate is 0.5 mEq/kg/hr — exceeding this risks fatal ventricular arrhythmias. Maximum concentration in fluids should not exceed 60 mEq/L without central venous administration.
Veterinary Research
Every formula is derived from peer-reviewed veterinary studies and clinical guidelines, not guesswork or generic rules.
