This contact-kill mechanism is a key differentiator from treatments that only work after a pest bites the dog. The formula begins working within 12 hours and provides 30 days of continuous protection per application. After 24 hours, the treatment becomes waterproof, maintaining effectiveness through water exposure.\u003c\/p\u003e\u003ch2\u003eUsage, Application, and Frequency Guidance\u003c\/h2\u003e\u003cp\u003ePart the fur between your dog's shoulder blades to expose the skin. Apply the entire contents of one applicator tube directly to the skin in one or two spots. Do not rub in - allow the product to spread naturally across the skin and coat. Apply once every 30 days for continuous protection. The treatment becomes waterproof after 24 hours - avoid bathing or water exposure during the first 24 hours after application. Safe for puppies 7 weeks of age and older weighing 4 lbs or greater. Do not use on cats - K9 Advantix II is toxic to cats.\u003c\/p\u003e\u003ch2\u003eFunctional Use\u003c\/h2\u003e\u003cp\u003eK9 Advantix II functions as a monthly topical parasite control treatment providing contact kill and repellency against fleas, ticks, and mosquitoes.
