Metronidazole is an antibiotic used to treat various bacterial infections in dogs. Proper dosage is crucial for effective treatment while minimizing side effects. This calculator helps determine the appropriate dosage based on your dog's weight and the specific infection being treated.
Introduction
Metronidazole is a broad-spectrum antibiotic that works by disrupting bacterial DNA synthesis. It's commonly used to treat bacterial infections in dogs, including:
- Gastrointestinal infections (e.g., Clostridium perfringens, Campylobacter)
- Urinary tract infections
- Skin infections
- Respiratory infections
The dosage of metronidazole for dogs varies depending on the dog's weight and the specific infection being treated. It's important to follow veterinary guidelines precisely to ensure effectiveness and safety.
How to Use This Calculator
Using our metronidazole dosage calculator is simple:
- Enter your dog's weight in pounds or kilograms

- Click "Calculate" to get the recommended dosage
- Review the results and administration guidelines
The calculator provides both the total daily dose and the number of doses per day based on standard veterinary recommendations.
Dosage Formula
The standard dosage formula for metronidazole in dogs is:
Dosage Formula
Dosage (mg/kg/day) = (Weight of dog × Recommended dose per kg) / 24 hours
Total daily dose (mg) = Dosage (mg/kg/day) × Weight of dog (kg)
Where:
- Weight of dog = Your dog's weight in kilograms
- Recommended dose per kg = Varies by infection type (see table below)
The total daily dose is then divided by the number of doses per day to determine the amount per dose.
Common Dosage Ranges
Standard metronidazole dosages for dogs vary by infection type:
| Infection Type | Dosage (mg/kg/day) | Doses per Day |
|---|---|---|
| Gastrointestinal infections | 20-40 mg/kg/day | 2-3 |
| Urinary tract infections | 15-30 mg/kg/day | 2-3 |
| Skin infections | 10-25 mg/kg/day | 2 |
| Respiratory infections | 20-40 mg/kg/day | 2-3 |
These are general guidelines. Always consult with your veterinarian for specific recommendations based on your dog's condition.
