How this works
The calculator converts your pet's weight to kilograms, applies the reference dose for the selected protocol, then divides by the product concentration to give you grams (powders/granules) or mL (paste/liquid).
The two protocols use different doses per administration:
- Every day (continuous): 10 mg/kg per dose, given once daily every day.
- 3 days on, 4 days off: 50 mg/kg per dose, given once daily on 3 consecutive days, then 4 days of rest, then the cycle repeats. This matches the anecdotal off-label cancer protocol (e.g. ~5.5 mL of Panacur liquid for an 11 kg pet at 50 mg/kg).
Always confirm the appropriate dose and schedule with your veterinarian before starting. Dosing may vary by species. Long-term or high-dose fenbendazole use has been associated with bone marrow suppression and liver injury.
