Overview
Panacur C is a fenbendazole-based canine dewormer sold as 2-gram granule packets, with this listing containing three packets that together treat a dog up to 20 lb over a 3-day course.
Fenbendazole is a broad-spectrum dewormer used in veterinary practice, and Panacur is Merck's branded granule form meant to be mixed into a dog's regular food. The 3-day dosing schedule is a defining feature: this is not a single-dose product like some over-the-counter dewormers.
- 2 gram packets, 3 included
- Fenbendazole active ingredient
- Mixes into moistened food
- Made by Merck
Who it's for
Dog owners treating or preventing common intestinal parasites who need a granule dewormer that mixes into food rather than a pill. Dosing is weight-based, so owners with dogs meaningfully over 20 lb will need to adjust packet count accordingly.
Pros and cons
- Granule form mixes directly into regular food
- Treats up to 20 lb per 3-packet set
- Widely used fenbendazole active ingredient
- Requires dosing on 3 consecutive days, not a single dose
Performance notes
The granules are mixed into a dog's usual food once daily for three consecutive days, with dry food needing to be moistened first to help the granules combine evenly. Consistency across all three days is central to how fenbendazole works, since it targets parasites through repeated exposure rather than a single knockdown dose.
