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.

  • Great product

    By on

    We switched from another topical to this about 6 months ago. Glad we did. It works great & the smaller amount of product makes it easier & less messy when applying. No issues with any fleas, flea eggs, ticks, mosquitoes or biting flies. We're in the South where all of these are present. Very pleased & love that we can choose single or combo packs & be on auto ship- one less thing to remember & dogs are always protected. We absolutely LOVE Chewy!! Finally, a fantastic place to shop for all things dog!

  • Pleasantly surprised

    By on

    I am pleasantly surprised with how affordable and more cost-effective Chewie.com has presented us with options for not only our dogs food but also their anti-flea, tick and mosquito medicine . We will next begin to look for their toys and treats as it is much more efficient and effective to shop on our cell phones as opposed to go to Petsmart . Petco or any store has never been an option.

  • Works well

    By on

    I only gave four stars because this product leaves a greasy spot where it is applied and I know you shouldn't give a bath too soon after application. Otherwise, it's easy to apply, good applicator and seems to work well. I love that it repels mosquitoes too. I used it last year and will use it again, I'm sure.

  • Always a great deal!

    By on

    This order for flea and tick treatment came super fast, as have my previous orders. The items are always exactly what I ordered and the price has always been very competitive on each order, as I show prices! Additionally, real live people email you back when you send Chewy an email, and they are very understanding and more than fair.

  • Went above and beyond my expectations.

    By on

    I normally wouldn't take the time to write a review for any product; however, this product was affordable and did an AMAZING job for my eight week old Great Pyrenees. He was an outdoor dog for the eight weeks prior to me owning him and came to my house INFESTED with fleas. He was covered in scabs from scratching and was a very unhappy puppy. I bought this product and didn't expect much to happen for a few hours as the box claims the product takes twelve hours to kick in, but 3-4 hours after I put it on I saw fleas JUMPING OFF my dog. One day after I put this product on my dog was completely flea and tick free and has been ever since. I highly recommend this product and will continue buying it I normally wouldn't take the time to write a review for any product; however, this product was affordable and did an AMAZING job for my eight week old Great Pyrenees.

  • This stuff works!

    By on Top 1000 Contributor

    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.
