Description

Flea, tick and mosquito bites can be very painful for your dog. Worse, those bites may expose your dog to irritation, itching and even deadly diseases. Fleas may cause Flea Allergy Dermatitis (FAD) and if ingested, fleas could cause tapeworms. A bite from an infected tick can transmit diseases, such as Lyme disease or Rocky Mountain spotted fever, to your dog. And mosquitoes may transmit heartworms or even West Nile virus to your dog. K9 Advantix II is a veterinarian-recommended monthly flea, tick and mosquito treatment for your dog that kills through contact. No biting required.

  • - Veterinarian-recommended flea and tick prevention for dogs and mosquito repellent for dogs

Negative reaction Chiweenies

Unhappy Dogs after Trying

1 month ago
Dogs had a very negative reaction and had to rush them to the vet after giving them several baths to stop this from irritating their skin. I normally used oral flea and tick medicine so if was definitely from applying this to their skin after reading the directions. Highly do not recommend this product.

No, I do not recommend this product.

[This review was collected as part of a promotion.] My dog is usually picky with taking any kind of medicine, but he was able to take this very well! He let me put it on him no issues and was easy to apply.

We use this during the summer and it works perfectly! I have 2 great pyrenees who love the dog park and hiking and neither have ever had a flea or tick when we use this.

Works perfectly at keeping away fleas and ticks. Its comes in a vial filled with liquid and you apply to your dogs neck. My dog hadnt experienced any reactions and it seems gentle on her skin.

I used this product. It is really working for my 60lb chow. Please follow the instructions when you apply it. Apply on a skin do not forget that. That product absorbs fast. My dog did not catch any fleas or ticks and we love hiking. Check on a box how often you need to apply the product.

And seems to work but my dog normally does not have a problem with fleas. It’s a good product highly recommend for your pet.

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
