How It Works
Dog medication dosing is weight-based — expressed as mg per kg of bodyweight. This calculator multiplies your dog's weight by the established therapeutic dose range to give the actual mg to administer. Always start at the lower end of the range and adjust under veterinary guidance.
Veterinary Research
Every formula is derived from peer-reviewed veterinary studies and clinical guidelines, not guesswork or generic rules.
