What is a Dog Medication Dosage Calculator?
A Dog Medication Dosage Calculator converts prescribed mg/kg dosing into practical mg-per-dose and mL-per-dose values using weight, concentration, and frequency.
Formula
Weight (kg) = Weight (lbs) × 0.453592 Dose (mg) = Weight (kg) × Prescribed mg/kg Dose (mL) = Dose (mg) ÷ Concentration (mg/mL) Daily Total (mg) = Dose (mg) × Doses per Day
Example
A 30 lb dog at 5 mg/kg with a 25 mg/mL liquid needs about 2.72 mg/kg × 13.6 kg? No—calculator avoids manual mistakes and outputs the precise mL per dose directly.
Common Applications
- Prescription double-checking
- Liquid dose measurement planning
- Refill timing estimates
- Caregiver handoff instructions
Tips
- Use a calibrated oral syringe for accuracy.
- Record dosing time and amount after each administration.
- Recalculate promptly if body weight changes.
Frequently Asked Questions
What does mg/kg mean in medication dosing?
It means milligrams of medication per kilogram of body weight. This standard format helps normalize doses across dogs of different sizes.
How many medications are included in this calculator?
This calculator includes 46 common veterinary medications organized into categories: antibiotics, NSAIDs, pain management, anticonvulsants, antiemetics, antihistamines, sedatives, antifungals, antiparasitics, cardiac drugs, diuretics, and gastrointestinal medications.
Why do I need concentration in mg/mL?
Concentration converts required milligrams into measurable liquid volume. Without concentration, you cannot safely measure the dose in milliliters.
Can I round the mL dose?
Only as advised by your veterinarian. Small rounding differences may matter for potent drugs or small dogs, so accurate syringes are important.
Does this calculator replace prescription guidance?
No. Use this only for planning and cross-checking. Follow your veterinarian's exact prescription and scheduling instructions.
How should I handle a missed dose?
Contact your veterinarian for specific instructions. Do not double-dose unless directed by a professional.
