Instructions

How to open:

  • 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.
  • The dog should be standing for easy application. The entire contents of the K9 Advantix II tube should be applied evenly on the top of the back from the shoulder to the base of the tail. 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. Do not apply an excessive amount of solution at any one spot that could cause some of the solution to run off the side of the dog.
  • Discard empty tube.
  • In cases of severe pest infestations, retreatment is allowable earlier than 4 weeks. Do not retreat more often than once every 7 days. After pest control is attained, return to a monthly retreatment schedule.

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 stuff works!

    By on

    I have tried other products that cost less and always end up going back to this. I have two Pugs; one puppy, one elder. They both had fleas. Walter, who is 10-months old, handled this like a dream. No side-effects whatsoever. Percy, who is 13 years old, was the same. I administered it and within a couple of days, the fleas were gone. I have to say that Chewy had the best prices on the internet. I shopped around just because this stuff is so expensive, but it is worth it. It's works and it works quickly.

  • Saved My Fur Babies

    By on

    We tried a brand name that starts with an "F" and it barely worked on my 5 miniature Schnauzers, since it had a good reputation I kept using it but it never worked. I was at my wits end, seriously in tears because my babies were so miserable. By the time, I saw a commercial for K9 advantix II my babies were covered in fleas from head to tail. I can't tell you what a relief it was to finally find something that actually worked and how gratifying it was to find dead fleas on their beds. I would laugh maniacally while vacuuming them up. =0)

  • K9 Advantix Works Best

    By on

    I have tried several different products over the past 12+ years and can say that K9 Advantix is the best overall product for my dogs (three miniature schnauzers). When using this product monthly, I have never found a tick on any of them, unlike some other generic/lower cost options (it should be noted that the current sale prices from Chewy make K9 competitive with everything). The added mosquito repellent also works quite well, I cannot recall ever seeing them scratching from mosquito bites, unlike myself. Wish they made this product for humans!

  • Best flea/tick meds, hands down!

    By on

    I've used other top brands in the past but none work as well as K9advantix II. I will stick to what I know works. Years ago when I was using Frontline, we had a flea outbreak in our home. I bought this, put it on all 3 dogs and the next morning I found dead fleas on their bedding. In no time at all, no more fleas....and I didn't even have to use a flea bomb. Also, chewy has THE best price around....not to mention the best customer service.

  • It's hard to rate 5 stars to any tick & flea product

    By on

    I use this as recommended. Once monthly. My dogs still scratch here and there but I can't say its because of ticks of fleas because I have no longer seen any on them since using the product. Both my dogs take benadryl for allergies and it's possible they scratch from allergies from day to day stuff. I do notice 1 week before the 1 month mark the dogs seem to scratch more as if the dose is no longer active or is very diminished. U still recommend this product over cheaper store brand stuff.

  • Works Great!

    By on

    I found this product to meet or beat all expectations! I have used it on all sizes of dogs, long and short haired. Those of you not getting good results need to familiarize yourself with this product before using it. Do NOT wash your dog just before applying the product. Apparently the oils in the dog's skin and coat are essential to the success of this product. I educated myself and compared ingredients in other products. If used according to directions, this one is a slam dunk! When the critters touch your dog's fur, their nervous system is overexcited, they get disoriented and paralyzed and fall off your dog and die...all before they get a chance to even bite them!

  • Not working well

    By on

    Savannah...11.5 lbs...just hit the mark for the weight minimum for this product. It did not handle the flea issue with her...her lower half of her body still had fleas...top half not... never have seen that before. My other dog...significantly heavier at 14 .4 lbs had no issue at all.

  • Love this product

    By on

    My family and I used to use Frontline but we have all switched to K9 advantix II as we have noticed it lasts a little longer for each of our dogs and has proven to work really well. I have never had a dog get sick from this product and as long as it works for them, I will continue to use it.

  • Works for Cindy

    By on

    This is the second year that I have used this product. Cindy is bothered by allergies and has not been able to have other products applied or oral. This product works great for her. No allergic reaction, no fleas, no ticks, and no ear mites. What peace we both are having.

  • Works Well

    By on

    Just give your dog a bath first, apply the medicine, and wellah... you will see a difference in 24 hours for sure. I find that it works longer than the time indicated. I have been able to apply it quarterly for my 3 dogs. The 1st time I used it, I gave to treatments, but my babies were suddenly infested when they found a dead opposum in the back yard... Eeek... but they are doing great now.
