What Is the Clavamox Dog Dosage Calculator?
Clavamox is a veterinary antibiotic combining amoxicillin and clavulanate potassium, commonly prescribed for skin, soft-tissue, and urinary infections in dogs. This calculator estimates the amount in milligrams (mg) your dog should receive per dose based on its body weight and the standard label dosing rate of 12.5 mg/kg given every 12 hours. It is an educational aid only — your veterinarian's prescription always takes priority.
How to Use It
Enter your dog's weight and choose kilograms or pounds (pounds are converted automatically). The default dose rate is 12.5 mg/kg, which matches the typical Clavamox package insert; adjust it only if your vet specified a different rate. The calculator returns the dose per administration plus the total daily amount across two doses.
The Formula Explained
The core calculation is straightforward: multiply the dose rate by the dog's weight in kilograms. With the standard rate, $$\text{Dose (mg)} = 12.5 \times \text{weight (kg)}$$ Because Clavamox is given twice daily, the total daily dose is double the per-dose amount. If you enter pounds, the tool first converts using \(1\ \text{lb} = 0.45359237\ \text{kg}\).
Worked Example
A 20 kg dog at 12.5 mg/kg needs $$12.5 \times 20 = 250 \text{ mg per dose}$$ given every 12 hours, for a total of 500 mg per day. A 10 lb dog converts to about 4.54 kg, giving roughly 56.7 mg per dose.
FAQ
How often is Clavamox given to dogs? Typically every 12 hours (twice daily), usually with food, for 5–14 days as directed by your vet.
Can I round the dose to fit available tablets? Clavamox comes in fixed tablet strengths (e.g., 62.5, 125, 250, 375 mg). Your vet will round to the nearest practical tablet size — do not split or adjust without guidance.
Is 12.5 mg/kg always correct? It is the common label dose, but some infections require higher rates. Always follow the exact dose and duration your veterinarian prescribes.
