  • Be sure tube is at bottom of pouch.
  • Using scissors, cut the pouch across the top and remove tube.

How to apply:

  • Use only on dogs.
  • Remove applicator tube from the package. Use scissors and peel down foil.
  • Hold applicator tube in an upright position. Pull cap off tube.
  • Turn the cap around and place other end of cap back on tube.
  • Twist cap to break seal, then remove cap from tube.

At each spot, part the hair until the skin is visible. Place the tip of the tube on the skin and gently squeeze to expel a portion of the solution on the skin.

Frequently Asked Questions

How is K9 Advantix II different from K9 Advantix?

With the addition of an insect growth regulator (IGR), K9 Advantix II kills all life stages of fleas. K9 Advantix II also prevents development of fleas, flea eggs, larvae (maggots), and pupae (cocoons), and prevents fleas on a treated dog from infesting your home.

What is the benefit of repellency?

Repellency helps prevent ticks, fleas, and mosquitoes from attaching, biting or feeding. A repelled parasite doesn’t bite or attach. If it doesn’t bite or attach, it can’t transmit the organisms that may cause disease.

What is the difference between K9 Advantix II and other tick and flea products?

K9 Advantix II repels and kills ticks, fleas, and mosquitoes. It repels biting flies and kills lice, too. Its repellency activity and broad spectrum make K9 Advantix II different from other tick and flea products.

Is K9 Advantix II waterproof?

Yes. There is no need to reapply the product after weekly swimming or a bath. For best results, use a non-detergent shampoo.

Can I use K9 Advantix II on my cat?

No. K9 Advantix II must not be used on cats because of a cat’s unique physiology and inability to metabolize certain compounds.

  • This definitely works

    By on

    I have a 90 pound lab and a 70 pound german shepherd. I applied this and I stopped seeing the fleas. However, after about two-and-a-half to three weeks later, they started coming back again. It says it prevents infestations for a month, but keep in mind it probably actually means up to a month. At least in our case. It's quite expensive but it does work if you're desperate. Which we were.

  • HUGE Chewy fan! Hate this product

    By on

    Honestly I had 100% intentions of purchasing K9 Advantage! I some how easily was confused with the whole "ends with x or g". I had no idea I'd made the mistake tiI i'd opened the package. By this time my dog was miserable;(had been using something for a few yrs that stopped working this summer) I just didn't have the heart to make him wait till I'd be able to buy the stuff I'd originally planned! (All my neighbors are using the name with a G and all seam to be working well) Figured it's very close in just about everything so I used it. After a few days Rocky was not scratching, he was sleeping better, seamed happier. Just 8 days after use the scratching returned, back to fighting fleas. So upset Honestly I had 100% intentions of purchasing K9 Advantage! I some how easily was confused with the whole "ends with x or g". I had no idea I'd made the mistake tiI i'd opened the package.

To many people trying to make a buck while cloaking themselves to good products hoping that, I(& you) Don't catch the screwup. Again- NOTHING TO DO WITH CHEWYS! They do their absolute best at being the best! Buyer be warned Advantix is not doing much in my neighborhoods! Would have been better trying to pick off and kill each little one that looked at my Pup: … more

  • Highly satisfied

    By on

    Took our 130 pound german shepherd to a family members in the country a week ago and he came back chewing non stop. Then we found the fleas. I ordered this product on a Friday morning, paid the standard shipping, received it the next morning on Saturday, gave him a quick dawn soap bath, treated him, and now Sunday is the sound of silence. No more constant chewing and scratching. Very happy.

  • Safest poison

    By on

    After trying to go the holistic route (M**** Top Spot is the best of those, but you have to combine that with the daily spray/flea collar/and comb for fleas...CONSTANT vigilance), I decided to go with chemicals. My dogs were suffering from fleas/mosquito/no-see-ums. Fipronil is not safe, so in my research I looked at Pyrethrins...tested on pregnant women, also pregnant dogs(ingested & put on skin) with NO effect on the fetus. Decided this is the poison that is the 'safest' for my dogs. Within a few hours, the itching stopped. No more fleas/no seeums/etc.

  • Flea control maybe? but not repellent

    By on

    I have only dosed my dog once with this and at first it was perfect but in the two weeks since I have seen fleas on him. The fleas appear slow and disoriented but they are still there. So I have had to bathe him once a week to keep the numbers down.

  • it works~!

    By on

    I had stopped using this - you could say I let my guard down since I'd never experienced a flea problem. My 3 big Dogs got fleas big time! Started them back on this and noticed tremendous difference in one day. It's going on 1 month now and close to being flea free. I feel like after the next dose my problems will be solved.

  • Works well....

    By on

    in tandem Sentinel. The latter will kill fleas, but does not repel them, or mosquitoes. Between the the products, my sense is my pet has 360 degree protection. Chewy's price is very reasonable for this product.

  • switched from Advantage 2

    By on

    I have bought Advantage 2 (6 doses package)for my GS for a couple of years, but found he still scratched and chewed himself a lot, it seemed the 6 dose Advantage 2 didn't work at all, so I decided to switch to this one for him to try. Just used once, 2 weeks ago, still do not know whether it works well or not, for he scratches himself and chews himself also but just less than before. Hopefully it will work.

  • So glad my mommy found Chewy

    By on

    I'm so glad our mommy found Chewy! Our family was battling the mean ole flea gang. Mommy had bought advantage from many other places but it took so long to get here that we just kept missing the date. Thanks to this magnificent place on her handy dandy light up music box, our flea fighting meds arrive on time. We are now flea free and loving it! Thanks Bayer and Chewy. Your devoted pet pals. ..Celie Wiggle, Jay Walker, Ben J Man, Theory, Tootsie, Vanilla and Chevy Rose.
