Rated 5 out of 5 by This product is awesome! We live in the country on a lake. K9 Advantix II gets rid of those pesky black flies as well as killing ticks, fleas and mosquitoes. Two thumbs up! March 29, 2012
Rated 5 out of 5 by Best on the market Our goldens have been on K9 Advantix II for a few years now. They have never had a flea on them and the occasional tick is dead by the time we find it. Chewy's price was so low that my vet wouldn't price match. December 29, 2012
Rated 5 out of 5 by Excellent Product This product not only kills ticks and fleas, but also repels. Have not found tick on dog at all and we live in the woods. July 24, 2012
Rated 5 out of 5 by Better then Frontline & Advantage Each person, product, pet & location are all different. Some people prefer 1 over the other, I prefer Advantix II. Where we live (in the sticks) is a lot of sand & with sand come sand fleas. These little boogars are the worse yet! Not to mention the numerous strays that get dropped off daily. This is the 1 product that actually works the way it was meant to. In the city, Frontline was the 1 to beat...but not out here. Frontline cant' lay a finger on these fleas...LOL. It works for the entire month +/- a day or so. And for the price, well.... July 18, 2014
