Description: Bayer's Quad Dewormer expands coverage beyond tapeworms alone, combining three active ingredients — praziquantel, pyrantel pamoate, and febantel — to target four of the most common intestinal parasites affecting dogs in a single chewable tablet: tapeworms, hookworms, roundworms, and whipworms. This broader spectrum makes it a useful option when an owner isn't certain exactly which type of worm their dog has, or when a vet or fecal test has identified more than one parasite type at once. The chewable tablets can be given directly in the mouth or disguised in food, and the product is sized into small, medium, and large dog formulas to ensure accurate weight-based dosing, safe for puppies as young as 3 weeks old and weighing at least 2 lbs. Like other over-the-counter dewormers, it doesn't require a prescription, making it a practical first step for routine deworming or a confirmed infestation. Owners should always weigh their dog carefully before dosing, since giving too little under-treats the infestation and too much increases the risk of side effects; a veterinary fecal exam remains the most reliable way to confirm which parasites are present before or after treatment.
