Panacur C is a granular, over-the-counter dewormer for dogs that contains fenbendazole as its active ingredient. Each box holds three individually sealed 1-gram packets, with each packet representing a single day's dose for dogs around 10 pounds. The granules are mixed into a small amount of the dog's usual food, moistening dry kibble if needed, and the dog must eat the full medicated portion for each of three consecutive days. It is intended for use in dogs only, including puppies six weeks of age and older and pregnant females. The product targets four common intestinal parasites and is part of a routine parasite control program rather than a single-dose treatment. No mixing equipment or assembly is required beyond stirring the granules into food. Store the unopened packets at controlled room temperature. Owners should weigh their dog beforehand to select the correct packet size and rounding up to the next size if the weight falls between increments.
