Dog Dosage Calculator

A dog dosage calculator for the standard veterinary dose math. Enter your dog weight and a dose rate in mg/kg, plus the concentration of the product, and the calculator returns total mg and volume in mL.

Formula

total dose (mg) = dose rate (mg/kg) x dog weight (kg)
volume (mL)     = total dose (mg) / concentration (mg/mL)

Worked example

A 12 kg dog with a 5 mg/kg dose rate and a 50 mg/mL product:

total dose = 5 x 12 = 60 mg
volume = 60 / 50 = 1.2 mL

Notes for dog dosing

  • Small breed dogs are not scaled-down large dogs. Some drug doses differ.
  • Always confirm the dose rate against a veterinary reference for dogs.
  • See our drug reference for source-linked values.
