K9 Advantix II Small Dog is a top-rated, veterinarian-recommended treatment designed to protect your dog from five common pests: fleas, ticks, mosquitoes, biting flies, and lice. Unlike other products, K9 Advantix II not only kills but also repels these pests, ensuring your dog stays safe and comfortable.

This fast-acting formula begins killing fleas within 12 hours of application, effectively halting existing infestations and preventing new ones. By killing adult fleas on contact, it stops them from laying eggs—no need for your dog to be bitten for the treatment to work. Regular monthly use of K9 Advantix II helps guard against flea-transmitted diseases like tapeworms, as well as conditions such as Flea Allergy Dermatitis and flea bite anemia.

K9 Advantix II's easy-to-apply, spot-on formula is more convenient than a flea collar and doesn’t require hard-to-swallow pills. Plus, it's fragrance-free and becomes waterproof 24 hours after application, making it suitable for both indoor and outdoor dogs.

This treatment is designed for dogs aged 7 weeks and older, weighing between 4-10 lbs. K9 Advantix II is available without a prescription in 2-dose, 4-dose, and 6-dose packs, so you can easily maintain your dog's protection all year round. After applying K9 Advantix II, your dog can immediately return to their favorite activities, from cuddling to running at the park.
