Overview
["This is the largest packet size in the Panacur C fenbendazole line covered here, with each of the three included packets holding 4 grams and sized for a dog around 40 lbs.

It's labeled for all life stages.", "It's also the most purchased of the three Panacur C sizes here, with an estimated 5,000 units bought in the past month and roughly 6,000 reviews at a 4.7 star average, making it a strong seller for owners of bigger dogs."]

Performance notes
As with the smaller Panacur C packets, this is a powder that needs to be mixed into a full meal and completely eaten to deliver the intended dose, which matters more with a bigger dog that might otherwise pick around food.
What buyers say
With about 6,000 reviews at a 4.7 star average and an estimated 5,000 units bought in the past month, this is the best-selling of the three Panacur C sizes in this roundup, consistent with it fitting a common larger-dog weight range.
What size dog is the 4 gram Panacur C packet meant for?
Each 4 gram packet is proportioned for a dog around 40 lbs. Smaller dogs are usually better matched to the 1 gram or 2 gram packets.
How is the dose given?
The daily dose is mixed into a small amount of the dog's usual food, moistened if needed, and repeated once a day for three days in a row, per the label.
Should I confirm the dose with a vet first?
This is not veterinary advice. For a dog with an unclear weight, health condition, or specific parasite concern, it's worth checking with your vet before starting the course.
