About Pet Medication Dose Helper
Converts a prescribed milligram-per-kilogram dose into the practical quantities you actually administer: milligrams per dose, millilitres of a liquid at a known concentration, and the tablet fraction. It is an arithmetic aid for a dose a veterinarian has already prescribed.
Formulas
Dose in milligrams
mg = body weight kg x prescribed mg per kg
Volume of liquid
ml = dose mg / concentration mg per ml

Assumptions and limits
- The result is derived only from the 5 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
- This is an arithmetic aid only and not veterinary advice. Never administer any medication to an animal without a veterinary prescription and explicit dosing instructions. Many human medicines are toxic to pets, and overdose can be fatal.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions
Can I split tablets to get the fraction shown?
Only if the tablet is scored and the medicine is not modified-release or enteric-coated. Splitting some formulations changes absorption or exposes the animal to a harmful dose.
What if the calculated dose seems wrong?
Stop and contact your veterinarian. Never adjust a dose based on this or any calculator - transcription errors in weight, units or concentration are the usual cause.
