Description

K9 Advantix II Extra Large Dog is the veterinarian-recommended formula that helps defend your dog against five pests: fleas, ticks, mosquitoes, biting flies and lice. And unlike other treatments, K9 Advantix II kills and repels fleas, ticks and mosquitoes. K9 Advantix II topical treatment gets straight to work killing fleas on dogs within 12 hours of initial application. This formula stops existing flea infestations and prevents new ones by killing adult fleas on contact so they can’t lay eggs and they don’t have to bite your dog to die. K9 Advantix II Extra Large Dog topical, spot-on formula makes application simple - going on in seconds. You’ll also love that K9 Advantix II is fragrance-free and waterproof after 24 hours of application. K9 Advantix II pest protection is effective on both indoor and outdoor dogs. K9 Advantix II Extra Large Dog is a trademark of Elanco or its affiliates.

  • IT works fast
Size: 1 Pack Style: XL Dog only
I just put it on my dog for the second time. I am thrilled with this stuff no more fleas. My dog is happy again. We ended up infested with fleas. My poor dog had bites all over his body, especially his rear end. He was going crazy and crying all the time I was trying everything on him, but I knew we had to get rid of the fleas. I tried for other products, not cheap and not good. Finally a product that does what they say it does. So easy to put on a few dots from shoulder blades to tail. My dog had no problems with it going on and evidently it doesn’t sting or anything because he was fine. The fleas are gone. It wasn’t just on him. FYI we have several indoor cats, who also ended up with them including babies. Fleas can be so hard to get rid of Buy this now if you don’t have them in your house. My dog is 80 pounds but I’ll tell you the price is worth it. I still have marks from getting bitten by the fleas. Oh yeah, they eat everything including us. ... show more

  • Works well
Size: 4 Pack Style: XL Dog only
I live my summers in the mosquito capital of the world I think! In Alaska, the mosquitos are so prevalent that on a sunny, non-wind day you would think that every mosquito in the world was there. I worried about my dog and mosquitos. This product actually works to keep those nasty creatures off of him. ... show more

  • Doesn't seem to work
Size: 6 Pack Style: XL Dog only
I have purchased this brand for many years and this year it does not work as well as in the past.

  • Works better than other treatments I've tried!
Size: 4 Pack Style: XL Dog only
Last year I used a different brand, which only lasted a week or so. The Advantix kept my dog scratch free, the whole month.

  • K 9 protection
Size: 6 Pack Style: XL Dog only
This product mentioned that it could also repel the fleas and some of the other bugs. The other one that I had been using, didn’t say that so I bought this time of course will tell Baxter is not outside a lot, but I also don’t want the fleas or any of the bugs in the house, they seem to be working. You apply a little different than the other things you put on. They are price but so is trying to ridge your home of fleas think they’re worth it good value to apply. ... show more

  • Not good for ticks
Size: 2 Pack Style: XL Dog only
Bought this as a supplemental tick protection for a trip in NC. My dogs are already on simparica, but I wanted more of a "repellant" for ticks. It didn't work. Dogs still got ticks crawling on them. Otherwise the product applied well, took a long time to dry and I was a bit concerned about us petting them esp the kids. I only used this on the dogs because we were away from the cats. Use extreme caution in household that has cats as this product is very very toxic to cats. ... show more
