How to Use the Metronidazole Dosage for Dogs Calculator
Using our calculator is simple and only takes a few seconds. Here’s a step-by-step guide:

This is usually expressed in milligrams per kilogram (mg/kg). Your veterinarian will provide this number, typically within a safe therapeutic range (e.g., 10–20 mg/kg). - Click the “Calculate” Button
The tool will instantly compute the total amount of metronidazole (in milligrams) your dog should receive. - View Your Result
The total dosage will be displayed clearly, so you can check it against your prescription. - Use the Reset Button if Needed
If you want to calculate for another dog or adjust the numbers, hit “Reset” and start again.
Practical Example
Let’s walk through a real-world scenario:
- Dog’s weight: 12.5 kg
- Dosage rate prescribed: 15 mg/kg
Step 1: Enter 12.5 into the weight field.
Step 2: Enter 15 into the dosage field.
Step 3: Click Calculate.
Result:12.5 kg × 15 mg/kg = 187.5 mg total dose
This means your dog should receive 187.5 mg of metronidazole per dose, as directed by your vet.
