Dog Bicarbonate Deficit Calculator
Calculate the bicarbonate deficit and sodium bicarbonate supplementation dose for metabolic acidosis in dogs.
What Is the Dog Bicarbonate Deficit Calculator?
Calculate the bicarbonate deficit and sodium bicarbonate supplementation dose for metabolic acidosis in dogs.
Calculate the bicarbonate deficit in a metabolically acidotic dog and the dose of sodium bicarbonate needed to partially correct it — with guidance on safe administration.
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 It Works
Bicarbonate deficit = body weight (kg) × 0.3 × (desired HCO₃ − measured HCO₃). The factor 0.3 represents the bicarbonate space (approximately 30% of body weight). Only 1/3 to 1/2 of the calculated deficit should be administered in the first 15-30 minutes — then blood gas reassessment guides further supplementation.
Bicarbonate therapy is reserved for severe metabolic acidosis (pH below 7.1, HCO₃ below 10 mEq/L) not responsive to fluid resuscitation alone. Target HCO₃ should not exceed 20 mEq/L in a single correction — over-correction causes metabolic alkalosis and paradoxical CSF acidosis.
Veterinary Research
Every formula is derived from peer-reviewed veterinary studies and clinical guidelines, not guesswork or generic rules.
