K9 Advantix II Flea, Tick & Mosquito Treatment for Medium Dogs 11-20 lbs (1-Month Supply)

The K9 Advantix II Medium Dog is a veterinarian-recommended formula that helps defend your dog against five pests: fleas, ticks, mosquitoes, biting flies, and lice. Unlike other treatments, this topical formula kills and repels fleas, ticks, and mosquitoes. The K9 Advantix II kills fleas on dogs within 12 hours of initial application, stopping existing flea infestations and preventing new ones by killing adult fleas on contact before they can lay eggs. This prevents fleas from biting your dog, which is crucial as fleas, ticks, mosquitoes, and other pests not only cause discomfort but may also transmit diseases.

Monthly use of K9 Advantix II is important to protect your dog against fleas that may cause the transmission of tapeworms. This formula also kills fleas that can cause Flea Allergy Dermatitis and flea bite anemia. The easy-to-apply, fragrance-free, and waterproof (after 24 hours) topical, spot-on formula makes application simple and convenient, without the need for hard-to-swallow pills or flea collars.

K9 Advantix II pest protection is effective on both indoor and outdoor dogs. Your dog should be at least 7 weeks old and weigh 11-20 lbs. to use the Medium Dog formulation. For the ultimate convenience in care, K9 Advantix II is available over the counter, without a prescription, and you can stock up with 2-dose, 4-dose, and 6-dose packs to ensure you never miss a monthly treatment.

Once K9 Advantix II is applied, your dog is ready to get right back to big-pup cuddles and racing around the park. K9 Advantix II Medium Dog is a trademark of Elanco or its affiliates, and the 30-day treatment and prevention protects dogs weighing 11-20 lbs. from fleas, ticks, mosquitoes, biting flies, and lice.
