How does K-9 Advantix work?

K-9 Advantix works by killing and repelling fleas and ticks on your dog. The active ingredients in K-9 Advantix are permethrin and imidacloprid. Permethrin works by paralyzing fleas and ticks, while imidacloprid works by interfering with their nervous systems. K-9 Advantix also contains a repellent, which helps to keep fleas and ticks off of your dog.

K-9 Advantix is applied monthly to your dog's skin. The product is absorbed into your dog's bloodstream and distributed throughout their body. K-9 Advantix starts to kill fleas within 12 hours of application and kills ticks within 48 hours of application. The product also repels fleas and ticks for up to 30 days.

K-9 Advantix is safe for use on dogs and puppies over 7 weeks of age. It is not safe for use on cats.
