Product Description
K9 Advantix II for Large Dogs is a veterinarian-recommended topical spot-on treatment designed to protect your canine companion from harmful pests. Specifically formulated for dogs weighing 21 to 55 pounds, this advanced solution provides broad-spectrum defense against five major pests: fleas, ticks, mosquitoes, biting flies, and lice. Unlike conventional oral treatments that require parasites to bite your pet to take effect, this topical formula works through contact, neutralizing pests before they can bite and cause discomfort or transmit diseases. This two-month supply package offers continuous, long-lasting defense, with each application lasting up to four weeks. The fragrance-free formula becomes completely waterproof within twenty-four hours of application, ensuring your active dog remains fully protected even during swimming, bathing, or heavy rain. It effectively stops existing flea infestations by killing adult fleas within twelve hours of initial application, while also breaking the flea life cycle by preventing new eggs from hatching. Ideal for Indian pet parents seeking premium, reliable pest control for their medium-to-large breeds, this over-the-counter solution delivers professional-grade protection directly to your home. Please note that this product contains permethrin and is strictly for use on dogs; it must never be applied to cats.

Q2. Do you also need to check for cat-safe alternatives or other weight ranges?
