Customers say

Customers overwhelmingly praise this flea and tick treatment for its exceptional effectiveness, with most reporting complete elimination of infestations and zero parasites after switching. Many highlight decades of consistent success, particularly in high-risk wooded areas, and frequently compare it favorably to other brands, noting superior speed and longevity. Reviewers also appreciate the added mosquito protection and stress-free application process. A small number report ineffectiveness or allergic reactions, but these concerns are vastly outweighed by the strong consensus that this is a reliable, go-to solution trusted for years.

Not very effective if you see fleas on your dog.

HeatherJ

[This review was collected as part of a promotion.] I was not too impressed with the effectiveness of the product. I had seen a few fleas on my dog and I couldn’t tell that the product helped much if any with removal, so duration and durability was not very good. I couldn’t tell that it had any scent. Application was very simple.

The tip applicator makes it easy to get in between my shepards thick coat. Since it’s in individual packages you done have to dose anything out. My dog hasn’t had any issues with fleas or tickets when this is administered on schedule.

[This review was collected as part of a promotion.] Love that I have an option to protect my large dog from fleas and ticks. The fleas and ticks have been getting worse each year with the warmer winters due to climate change. Have to protect the pups!

[This review was collected as part of a promotion.] Easy to apply with the squeeze bottle. No weird texture or smell when applying. My dog didn’t even notice me put it on her. Didn’t make a mess or anything!

Good but pricey

[This review was collected as part of a promotion.] The only reason I didn’t give this 5 stars is because of the price of I had bought it myself. It is very easy to use and convenient. I think it works well, but the price would be a deterrent for me.

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
