Protect your dog with the Panacur C Canine Dewormer. Used to treat and control hookworms, roundworms, Taenia Tapeworms and whipworms, this can be used to treat an active case of worms or as a precaution to prevent dogs who might be likely to develop them. The active ingredient fenbendazole is approved by the FDA, and it works by binding to the parasitic proteins, which leads to damaging the structure and the transport function of its cells. It’s easily administered by mixing the packet of powder with food, and it’s recommended to use one gram per 10 pounds of body weight. The three count allows you to use once per day for three consecutive days, which is one complete treatment. For use in dogs only.
