  • 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.

  • K9 Advantix Worked! Frontline Failed!!

    By on

    After discovering my dog had fleas, I bought some Frontline Plus and used that on him for three months, consecutively. His flea problem only got considerably worse. I purchased three more months of Frontline Plus and applied it, but still no improvement; and the infestation had actually gotten worse. I called my vet and they advised me NOT to waste anymore money on the Frontline, as they had stopped using and selling it due to the fact it simply just did not work any longer. They suggested K9 Advantix II which I bought and applied. After just a day or two, all the fleas were gone!! I was amazed and relieved the fleas were finally gone. After all the money I spent on Frontline Plus and it NOT After discovering my dog had fleas, I bought some Frontline Plus and used that on him for three months, consecutively.

After all the money I spent on Frontline Plus and it NOT WORKING AT ALL(ironically the Frontline is more expensive and you only get three applications as opposed to four applications in the K9 Advantix II), I began to desperately fear nothing was going to work until I tried the K9 Advantix II. I was so relieved and grateful for this product that I called Bayer, the company that makes Advantix and told them what a wonderful product they have and thanked them emmensely! I had used Frontline Plus in the past, successfully, so I was unpleasantly surprised when it did not work at all this time; but now, I will never use anything but K9 Advantix II for my dog, and Advantage II for my cat. Both products are affordable and immediately and completely eradicated all the fleas!!! … more

  • The Best Deal Ever!!

    By on

    So I have a new puppy and I know flea and tick and be very expensive. In my opinion this is the best flea and tick prevention product out there. The problem was everywhere I went to shop for it, it was super expensive, like almost $100 for 6 months. On chewy i saved a TON of money getting it for a little over $50 for 6 months with free 1-2 day shipping and a discount for autoship. You can't beat this. I love Chewy.com

  • Flea infestation is worse!!!

    By on Top 100 Contributor

    I have been using this for 5 months waiting for results. Sometimes for about 3 days after the treatment there are less fleas, but they ALWAYS come back in huge amounts. Thankfully chewy has a great return policy in case you are unhappy with a product. Overall, I would not recommend this to anyone in hopes of ridding fleas.

  • Didn't work for us

    By on

    My dog definitely doesn't have a serious flea infestation but he does still gets multiple fleas on him. He's highly allergic to flea bites so it's an issue. My assumption is that this isn't strong enough for states with high flea populations like California

  • K9 Advantix II works!

    By on

    We were looking for a topical that would not only control fleas and ticks, but also mosquitos. K9 Advantix works and the mosquitos that took to munching on my dogs before now tend not to land on them anymore. YEAH!
