Customers say

Customers overwhelmingly praise this product for reliably preventing and eliminating fleas and ticks, with most reporting zero infestations after consistent use. Many highlight its superiority over competing brands, noting it kills fleas faster and provides longer-lasting protection even in high-risk wooded areas. Reviewers emphasize deep loyalty, using it for years across multiple dogs and stating they wouldn't switch. An added benefit of mosquito repellency enhances satisfaction for many. A small group reports continued infestations or allergic reactions despite proper application, though these represent a minority compared to widespread positive feedback.

Never had any fleas or ticks on my dog after having this. We live in a rural wooded area and he runs constantly, yet we have never found a flea or tick on him. It’s last longer than the time it says as well

[This review was collected as part of a promotion.] Haven’t had any issues with fleas or ticks, and my pup has a lot of interaction with other dogs in daycare, so it seems to be working. It’s easier to use and it’s a good option for dogs that don’t like to take pills

[This review was collected as part of a promotion.] K9 advantix worked well on my dog to repel fleas and ticks. The medication was simple to apply and I did not notice any negative odor from it. I will definitely be using this product again.

[This review was collected as part of a promotion.] While there isn’t many ticks where I live at the moment, my dog seemed to take this well. I haven’t seen any ticks or fleas on him since. There hasn’t seemed to be any side effects and it’s compact making it easy to store.

This is the only product I use now it works great I have used other products but they did not works as good as this product and it helps me to get the problem solved without going to a vet and my dogs don't mind it at all I will never buy anything else. My dogs don't scratch all the time now and it is easy to apply to my dogs

Questions

1 - 10 of 96 Questions

should I bathe my dog before applying

  1. Yes! I bathe my dog before application.just make sure his fur is fully dry before you apply it!



Does it kill/ repel tapeworm ?

    I applied K9 Advantix II for small dogs (4 - 10lbs) to my toy poodle. He's oatmeal color fur. After the application, we noticed his fur on his back where the three spot applications were, turned grayish brown in a strip. What to do with the discoloration?

    1. Give your dog a bath no less than 24 hours after application. The stripe will go away and they'll still be protected. For the medication to be effective, they can't get wet for 24 hours application. The topical does pick up dirt and fuzz, but after you bathe them it will be gone.



    I have a 50 lb pit bull. Looking for good flea protection. He scratches often. Would advantix work?

    1. Advantix also repels pests.  Most flea treatments only kill fleas when they bite.  So Advantix may work for your dog. 



    What is the mm in large vs extra lg?

    1. XL: 4.0mL (0.135 fl. oz.) L:   2.5mL (0.84 fl. oz.)



    how many ml contain a dose for medium dogs?

      My dog weighs 150 lbs. how much do I need to use?

        Wts better advantage or advantix

        1. Advantix



        Hello my dog is 11.3 pounds should I use the small or medium one?

        1. Simple, don't use it. Use vectra instead



        I am looking something against the mosquitoes, we live in a hot, humid place and my dog is old, he doesn´t move a lot so the mosquitoes are a nightmare! This product works well for this problem??

        1. yes me and my 2 pups we go hiking alot in the woods the mosquitos will float around the pups ive been using this flea meds for 10 years never had a problem with fleas ticks and mosquitos i always wash the pups wait till next day and apply k9 advantix 2
