How to apply:

  • Use only on dogs.
  • Remove applicator tube from the package. Use scissors and peel down foil.

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.

  • Didn't work

    By on

    I've had excellent success with k9 advantix in the past, but recently I have found it to be ineffective. The day after I applied the treatment, my dog went on a hike. The following day I found a tick latched on. For the next week or so, I've found numerous ticks. The main reason I purchased this was to prevent ticks and the diseases they might carry. I'm not sure if I'd purchase it again.

  • Love this product

    By on

    This product includes protection of mosquitoes along with all stages of fleas and ticks. Have had great results with my 2 pittbulls ( short hair) and my chow/lab (full thick hair) each of which is over 75lbs. Have seen no side effects and have used this product for 3 years now. Chewy had great price and free shipping!!

    I noticed that this gives a financially challenged budget a sure fit. Most company's charge more to buy less!! This will keep a lot of customers! Hope this method catches on - people will be more apt to take better care of their pets

  • good stuff

    By on

    I did use another product years ago and was unaware that the formula had been changed. Our GSD and all 3 indoor cats got not only fleas but tape worms as well. It was a nightmare! K9 A II is the only thing I'll use. I tried briefly the Trifexis but the dog refused to eat it and it required a separate tick collar that had to be worn a week before going out into the field. No, no, no. Back to K9 A II to stay. Good luck with the rest. By the way, we live in the Pacific Northwest forest.

  • Great Product!!!

    By on

    The flea season came on with a vengeance and so being the mom of 5 German Shepherds who go out and play and come in we gave this a try and are Ecstatic about the results. Haven't seen any scratching or visable fleas on my babies. I would definitely recommend to others who want the protection for their furry children. Thanks Chewy for another super product at a great price !!

    In and out of the ocean, lakes, rivers, and through the woods...that's the praises we sing as Advantix Plus II stays on our 9 year old lab mix & works!! Chewy's, the most economical place to purchase it, that I have found.

  • Really works!

    By on

    I have two large dogs (about 100 lbs each) and the tick numbers have really exploded in the Northeast this spring. I received my package within 48 hours of ordering it. So far, over the last month since I applied the treatment, the number of ticks that I have found on my pups have dwindled significantly. This treatment works really well and I am very satisfied with Chewy and with this product.

  • BEST STUFF EVER

    By on

    I have 4 dogs and what I dog is get the largest pound k9 advantage and split it into four with a syringe no needles of course and put it onto each dog. I have never had a flea problem ever. I have been using this for about 11 years. this is the best flea medicine ever to me. Plus I have 5 cats and they are all inside and I don't use anything on them and only see a flea on them once in a while. BEST STUFF EVER TO ME............

  • Great against ticks!

    By on

    K9 Advantix works great for our GSD. We live in a rural country area with lots of ticks. If we go past one or two days on monthly application, ticks show up on the dog. So we know to stick to the 30 day schedule.

  • Use on all our dogs for years!

    By on

    Where we live, our dogs need the protection this product provides especially from the ticks, mosquitos and biting flies. Plus since we live near a lake we also need it to be waterproof. We have never had any issues since using this product and it's the only one that we will use.
