K9 Advantix Flea Control is a once a month topical application product that kills and prevents potentially diseased fleas, ticks, and mosquitos. K9 Advantix kills almost all feals within 12 hours of the first application. This product should only be used on dogs and puppies of at least 8 weeks of age. Water does not affect the treatment, so the dog can be washed without diminishing the effect of the topical application. K9 Advantix is not intended for cats of any age so do use it on them.
