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.

    Are cheap brand we have bought for years failed us.Both my 100 lbs dogs got fleas. So after 2 weeks of flea baths we got them under control. For the application process unlike are old brand the twist cap has a hole to open the top of the tube up. The tip has a cup on it so applying it to the skin and slight moving it in a circle insures skin contact. Then a light squeeze a controllable amount comes out. I love this design. For how it works. I can not say yet. Flea and tick season has passed but we treat year round. I will update next spring when the darn pest return..but based off reviews and my vet this is suppose to be a great product.

  • Did not work, Item came open.

    By on

    the box was already opened. I am not sure if it was a returned item. I was a little hesitant when i saw that but the tubes themselves where sealed so i proceeded to place them on my German Shepherd. Around 6 days later i noticed a brand new tick on my dog and had to remove it myself. The following day i found another tick on my dog. Ive used this product before from the pet store and never encountered this problem. I am not sure why this time it did not work on my dog. Needless to say I will continue buying Flea & Tick prevention from my local pet store.

  • Highly recommend K9advantix II

    By on

    My dogs were going crazy scratching. This came on all of a sudden. Upon checking them, I found Fleas. I bathed them in Dawn to kill the Fleas. When they were dry I applied the K9advantix II and They were flea free in just a few days. It took only a few days for the fleas in the house to die. We have had no further issues. We did subsequently bomb the house to help the pets. We have a beagle and a cocker spaniel. K9advantix is a very good product. You won’t go wrong purchasing and applying this product. It truly works.

    I have been buying this flea med for years for my standard poodle. I always Bought the product from my vet and received 2 free from the company. Just recently the company stopped the 2 free When you bought a 6 pk but the price remained the same as before over $100. Then I ordered the flea med from chewy Which was an excellent price for the same product saving me $40 plus. I will continue buying from chewy.com I received the product within 2 days of ordering. Will definitely recommend this product at this web site. Thank you

  • NEVER GOING BACK

    By on

    So originally I try to go as "natural" as possible, like tea tree oil or organic sprays to keep bugs pff the pack but... This year we moved, and now there is not only a huge yard but a huge amount of fleas, ticks and mosquitos.. . even limiting the dogs from going outside wasn't helping so we tried this treatment for my 80lb American bully and 8lb Chihuahua.. this stuff is absolutely amazing and there is no going back. I wanted to wait a bit before I actually wrote a review and five plus months into it and we have yet to see fleas , ticks ,etc. We have also been treating the yard as well and we have never been happier. I would highly recommend this !!!!!

  • It works....

    While I don't like to put poisons on my golden retriever (that is why it is 4 stars and not 5--it is a poison), k9 advantix does work. I am most concerned with ticks. In New Hampshire, ticks--especially deer ticks are terribly abundant. April to June and then mid September to mid November are especially bad. The ticks are so tiny that it is impossible to find them in a double-coated dog who goes through the woods daily. K9 Advantix kills and I have noticed it seems to repel as well. My golden has had reactions to frontline, so with advantix she seems to be ok. The natural oils, etc., are not enough protection. I buy the 55 lbs and over and apply half the vial.

  • SO VERY HAPPY SO FAR

    By on

    THIS HAS TO BE THE BEST I HAVE ORDERED SO FAR. MY DAUGHTER TOLD ME THIS MORNING SHE PUT THE K9 advantix ON OUR 2 PITTIE BABIES YESTERDAY. TODAY SHE WOKE UP WITH HUNDREDS OF DEAD AND DYING FLEAS ALL OVER HER BED AND SOFA. I AM THRILLED THAT WE FINALLY FOUND SOMETHING THAT WORKS. I HOPE AND PRAY IT KEEPS DOING THE JOB. I WISH ADVANTAGE FLEA FOR CATS HAD A FLEA and TICK INSTEAD OF JUST FOR FLEAS. WE HAVE 12 CATS AND LIVE IN THE WOODS. THE FLEAS AND TICKS ARE AWFUL THIS YEAR. THANK YOU CHEWY WE LOVE YOU

    I have been using Advantix for years. What I really like about this product is that it repels the ticks. I have not had any problems with ticks jumping on my dogs since I switched to Advantix! I would definitely recommend it!!

  • Flea, ticks AND mosquitoes!

    By on Top 100 Contributor

    We have used K9 advantix II since 2005/6 and it's always worked wonderfully. Originally we were going to get another flea/tick treatment but the vet was out and offered us this one for the same price. The other one didn't repel mosquitoes like this does so we were glad they offered this one and it's always been our go to.

  • No llve fleas !

    By on

    Excellent price with coupon from the mail and auto refill. We were looking to change brands to see if a new treatment might be more effective. So far it is working. Olivia showed no visual negative signs of intolerance to the treatment. No visible fleas or flea "dirt". Rapid order processing and shipping. Thank you
