TL;DR: K9 Advantix II is a monthly spot-on flea and tick topical for dogs 8 weeks of age and older, applied between the shoulder blades to affect fleas, ticks, lice and mosquitoes on contact — no bite required. It comes in four weight-based sizes (Small, Medium, Large and X-Large Dog) and is not for use on cats.
Because K9 Advantix II works on contact, parasites are affected before they bite. That contact action makes it a common choice for dog owners managing peak flea and tick season.
