Each monthly dose works on contact to kill and repel fleas, ticks, mosquitoes, biting flies, and lice without your dog ever needing to be bitten.

Kills Fleas Fast, Stops the Life Cycle Cold

K9 Advantix II doesn't just treat the surface — it eliminates fleas at every life stage, including eggs, larvae, pupae, and adults, breaking the infestation cycle before it can take hold in your home. Fast-acting within 12 hours of application, each dose provides a full 30 days of continuous protection. The waterproof formula stays effective even after baths or rain, so your small dog stays protected no matter what the day brings. It also repels and kills ticks that carry Lyme disease and other serious illnesses.
