This 5-pack of Panacur C bundles five separate boxes of 1-gram fenbendazole packets in one order, making it a practical bulk buy for multi-dog households, and its 4.6 star average across 1,133 reviews shows the formula has a long track record.

Skip if
You only have one small dog and just need a single course, since a smaller single-box size will likely cover you for less money.

Overview
["Each of the five boxes in this pack holds three 1-gram fenbendazole packets, with Panacur's own dosing guide sizing one packet to roughly 10 lbs of body weight per day over a 3 day course. That structure makes it easy to portion out by your dog's weight without cutting or measuring loose powder.", 'The label lists it as suitable for dogs 6 weeks of age and older, including pregnant dogs, and Panacur recommends mixing the daily dose into a small amount of regular food. At $43.36 for five boxes, the per-box cost works out lower than buying single boxes one at a time.', 'With 1,133 reviews holding a 4.6 star average and around 600 units bought in the past month, this is one of the more established options in the Panacur C lineup rather than a new entrant.']

Performance notes
Fenbendazole is dosed by weight over three consecutive days rather than a single dose, so the multi-box format here suits dogs that need repeat courses or households running more than one dog through a course at the same time. Mixing into a small amount of regular food is the labeled method, and dry food may need moistening to help the packet blend in.
What buyers say
A 4.6 star average across 1,133 reviews and roughly 600 units bought last month points to a steady, repeat-purchase pattern rather than a fad product, which lines up with Panacur C's long-standing reputation in this category.
The listing includes five boxes, each with three 1-gram packets, for a total of 15 packets across the pack.
Is this the same formula as other Panacur C sizes?
Yes, it's the same fenbendazole-based Panacur C formula, just bundled as five boxes instead of one, which can work out cheaper per dose if you need it regularly.
Can I use this on a pregnant dog?
The label lists it as suitable for dogs 6 weeks and older including pregnancy, but always confirm dosing and timing with your vet for a pregnant dog.
