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. 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. For dogs and puppies 7 weeks of age and older.
