THIS STUFF IS A LIFE SAVER! I have 3 Huskies and I know with this stuff that I won't have to worry about fleas and ticks. I with see dead ticks on ground and I know the product is doing its job. I mean I dont have time to constantly be checking each dogs long thick fur for ticks so I have peace of mind knowing that this stuff will get all those creepy crawlies for me. I have tried so many other brands for my dogs this is the only product that takes care of all of them for me

After discovering my dog had fleas, I bought some Frontline Plus and used that on him for three months, consecutively. His flea problem only got considerably worse. I purchased three more months of Frontline Plus and applied it, but still no improvement; and the infestation had actually gotten worse. I called my vet and they advised me NOT to waste anymore money on the Frontline, as they had stopped using and selling it due to the fact it simply just did not work any longer. They suggested K9 Advantix II which I bought and applied. After just a day or two, all the fleas were gone!! I was amazed and relieved the fleas were finally gone

When we first got our dog, the shelter said they used frontline on him the week before and that we wouldn't have to worry about ticks. Well, they were wrong. We took him to a national park near by and eventually came home with more than a dozen ticks in his ears and between his toes. I applied K9 Advanticks and within 12 hours, all of the ticks were dead and gone. Life saver.

I switched to Advantix after doing a decent amount of research. I had previously used another brand, which came in an oral form, and not only did my Shiba hate the taste, but he also would still get itchy. While the skin absorbing liquid form of Advantix can be a challenge to administer at first, it is worth it. It kills the broadest variety of buggers, and is one of the least toxic options on the market. Highly, highly recommend. K9 AdvantixA II Flea & Tick Dog Treatment

We had issues with our last flea & tick medicine not working any more! I did some research and bought K9 Advantix in the hope that it would cure my dog’s scratching and fleas. It worked wonders!! Very fast acting and super easy to apply. I’d highly recommend this brand over any other.

This is my go to flea and tick treatment for my Boston terrier puppy Capone. I can usually find it on sale at Persmart and I think the quality is much better and safer than the other less expensive brands. It's top recommend by my vet and includes fleas, ticks, and mosquitoes.

The K9 Advantage A ll Flea &Tick Dog Treatment has worked wonders for my dogs. Apply following the instructions in the beginning of the Flea and Tick season and I have never had any problems afterwards. My dogs all have sensitive skin and none of them have had a reaction to this formula. Of course all dogs c are different and you may want to consult with your veterinarian if you have any questions or concerns. I am able to purchase this product at my local Shoprite and Petco and it is no more expensive than the other brands that are sold in my area.

This product works the best on my dog. He doesn’t get fleas and ticks much but when he does this does the best works than any other products I have tried. I usually buy this at my local Petsmart store.

Hands down, this is the best flea and tick prevention available in stores. I live in the south, and it is hot for most of the years. That means fleas and ticks! Advantix keeps my dogs safe from fleas and ticks with relative ease. Just apply once a month, and they are protected. Definitely recommend

The ONLY flea and tick medicine that works. We live in the woods and we have all different types of species of ticks, and this brand is the only brand that keeps our dogs from itching all summer long. Don't be fooled by other brands that are 20$ cheaper. Just spend the money and get what's good.

Does this work pretty well? my dog has long hair so it's hard to see the ticks sometimes. I'm not happy with the current tick six that I use.
