Fenbendazole Dosage Calculator
The Fenbendazole Dosage Calculator estimates the calculated medication dosage amount per administration based on animal weight and product concentration. This tool helps pet owners and livestock farmers aim to provide parasite treatment without risking underdosing or harmful overdoses. Whether you are treating a dog for roundworms, deworming a herd of goats, or managing a Giardia protocol, this tool simplifies complex math. It provides calculated results for liquid suspensions, powders, and pastes to keep your animals healthy and parasite-free.
Always monitor the animal after administering the first dose to ensure they consume the full amount and watch for any adverse reactions.

How Medication Dosage Amount Is Calculated
The medication dosage amount represents the estimated volume or weight of the specific drug product it may be helpful to give your animal per dose. Calculating this correctly requires converting the animal's body mass into the total milligrams of active ingredient needed, then translating that back into the specific product you have on hand.
(Weight in kg × Dosage mg/kg) ÷ Concentration = Dose Amount
Where:
- Weight = Animal's weight in kilograms
- Dosage = Target dosage rate (usually 50 mg/kg)
- Concentration = Medication strength (e.g., 100 mg/mL)
- Dose Amount = Volume (mL) or weight (g) to give
- Convert to Kilograms: First, ensure the animal's weight is in kilograms to match the standard dosage metric.
- Calculate Total Milligrams: Multiply the weight by the target dosage (e.g., 50 mg/kg) to find the total active drug required.
- Determine Volume: Divide the total milligrams by the medication's concentration to find the estimated mL, grams, or tablets to administer.
What Your Medication Dosage Amount Means
This number provides an estimate of how much of the product (like Panacur or Safe-Guard) to draw into a syringe or scoop out for each dose. It bridges the gap between the scientific dosage rate and the physical product you purchased.
Standard Deworming Protocol: If your result is 10 mL of liquid suspension for a 20 kg dog, this amount is typically given once daily for 3 consecutive days. This standard schedule effectively clears common roundworms and hookworms by catching the parasites as they hatch.
Treating Giardia or Lungworms: For tougher infections, your daily dosage amount might remain the same, but the duration extends to 5 to 10 days. Ensure you have enough total supply calculated before starting this longer protocol.
Livestock and Large Animals: For horses or cattle, the result will often be a large weight in grams (e.g., 25 g of paste). Use the calibrated mark on the paste syringe or a gram scale for accuracy, as visual estimation can lead to underdosing.
