Ingredients and Formulation

K9 Advantix II is a topical parasite control solution formulated with Imidacloprid, Permethrin, and Pyriproxyfen. These active ingredients work together to kill adult fleas, ticks, and mosquitoes on contact, while also targeting flea eggs and larvae to help break the flea life cycle. The formula is applied directly to the dog's skin and becomes waterproof within 24 hours of application.

Usage, Application, and Frequency Guidance

Apply K9 Advantix II once monthly by parting the dog's fur and applying the entire contents of one applicator tube directly to the skin, typically between the shoulder blades. For extra large dogs, apply the full tube contents as directed on the label. The product becomes waterproof after 24 hours. Do not apply to wet dogs or allow the dog to swim or be bathed within 24 hours of application. Reapply every 30 days for continuous flea and tick protection.
