Custom Medication Dosage Calculator

Calculate the correct medication dosage and volume based on your pet's weight, the prescribed dose, and medication concentration.

Formula & Notes

Formula:

  • Total Dose (mg) = Weight (kg) × Dose (mg/kg)
  • Required Volume (ml) = Total Dose (mg) ÷ Concentration (mg/ml)

Example:

Weight: 10 kg, Dose: 20 mg/kg, Concentration: 100 mg/ml
→ Total Dose = 10 × 20 = 200 mg
→ Volume = 200 ÷ 100 = 2 ml

Important Notes:

  • Use actual weight (ideal weight is only for specific medications)
  • Ensure concentration is in mg/ml
  • Results are rounded to 2 decimal places
  • Always verify calculations with a veterinarian
