Product Description
K9 Advantix II Large Dog is the veterinarian-recommended formula that helps defend your dog against five pests: fleas, ticks, mosquitoes, biting flies and lice. And unlike other treatments, K9 Advantix II kills and repels fleas, ticks and mosquitoes. K9 Advantix II topical treatment gets straight to work killing fleas on dogs within 12 hours of initial application. This formula stops existing flea infestations and prevents new ones by killing adult fleas on contact so they can’t lay eggs and they don’t have to bite your dog to die.
Fleas, ticks, mosquitoes and other pests not only cause discomfort; they may also transmit disease. Monthly use of K9 Advantix II is important to protect your dog against fleas that may cause transmission of tapeworms. This formula also kills fleas which may cause Flea Allergy Dermatitis and flea bite anemia.
That’s why K9 Advantix II Large Dog topical, spot-on formula makes application simple - going on in seconds. It's easier than a flea collar and there are no hard-to-swallow pills. You’ll also love that K9 Advantix II is fragrance-free and waterproof after 24 hours of application. Check the product label for information on application and potential side effects.
K9 Advantix II pest protection is effective on both indoor and outdoor dogs. Your dog should be at least 7 weeks old and weigh 21-55 lbs. to use K9 Advantix II Large Dog.
For the ultimate convenience in care, K9 Advantix II is available over the counter – no prescription needed. And, you can stock up with 2-dose, 4-dose and 6-dose packs so you never miss a monthly treatment. Once K9 Advantix II is applied, your dog is ready to get right back to big-pup cuddles and racing around the park.
K9 Advantix II Large Dog is a trademark of Elanco or its affiliates.

This was the most effective. Within 32 hours of an application, I saw the fleas fall off. They were still alive when they fell off but obviously struggling so the medication was working. I got the small dose for my 10lb dog and the large dose for my 23lb dog. Cheaper than the oral tablet you get a vet prescription for and easy to order with subscription
UPDATE AS OF JULY 2013: I have brought home a 4 pound Pomeranian since my original post. I stand by what I stated in my previous post: this product works well for fleas, ticks, and mites in the warmer climate of middle Georgia in which I live. Barnaby, my little Pomeranian, has not had an adverse reaction to this medication, and Fluke, my lab/pit mixture, remains free of fleas and ticks, all the while not exhibiting any negative symptoms. For my little Pomeranian, I applied the medication to 4 separate places along his back, again to not have too high of a concentration in any one area. I purchased the smallest dose currently on the market, and although it was a little high for his small stature, it did not seem to phase him in any sort of negative ways. I wait, at a minimum, 72 hours before bathing my dogs, and I also do not bathe them for at least 5 days prior to application of the medication, as the oils within a dog's skin distribute the topical treatment. My dogs tolerate this medication well, and I have not found a flea or tick on either of them since I began using this product; however, I still will caution potential purchasers of this product: this product may not work well for your dog, just as some medications may not work well for you. Please, before you condemn the product as unsatisfactory, try to determine, and this may require the aid of a veterinarian, what your particular dog requires based upon breed, climate, and tolerance to topical flea prevention. I can only relate that this product works well for my larger dog and also my smaller dog within the area in which we currently live. Again, I hope that my update as to the effects of this product upon my smaller dog is helpful in your search for the right fit for your dog.
For anyone looking for full 4 weeks of perfect coverage, it just doesn't exist. Any topical solution will weaken as you near the 4th week but I have found Advantix 2 to be GREAT. This is a great Seller and cannot beat the price. This is my second time purchasing from this seller on Amazon for price but also quality of product not sold nearing expiration. Expiration doesn't MEAN BAD it means Weaker.
OK... SO! What about Irritated Skin!?
Don't BUY IT if your worried about that! Some dogs are extra sensitive or ALLERGIC. DONT buy a topical solution if that is a huge concern. IT DOESN'T MAKE THIS A 1 STAR product because your dog is allergic or sensitive. For god sakes, you are putting poison on them and that includes in any brand unless your getting a prescription for a Pill. Then there are other possible side effects. Accept That. Anything you choose has Pro and Con's.
My dog has sensitive Skin. She will get a little pink when I use ANY topical solution. However Advantix 2 is well known for being kinda strong. So how do I manage it for my Furbaby??? Easy. Take the time to put the solution on in several places. NOT JUST ONE BLOB, because you're too lazy.
I skip the base of the tail. I never understood this. My dog can lick there all she wants. But I go from base of head at the back of the skull and ever couple inches I squirt a little down till I get between the shoulder blades and even so much as a little bit below that on her back.
This helps spread it out and not irritate her and make her itchy. Then again, my pup has allergies and she's on Zyrtec daily. But when I use to not spread it out she would seem uncomfortable, now she is fine with it. She is just sticky for a day. A Con is Advantix 2 is a little greasier and you get More of it. But frontline barely gives any and never seems to work past 2 weeks. So take your pick!
After a day, I brush her out and there is no more sticky. I wait a week instead of 48 hours to bath her. I don't notice any lack of flea control after a bathing.
I really think this product works for anyone in areas where Frontline is losing its effectiveness. Also, heartworm is a billion dollar scare tactic. The idea of it is terrifying however, it is also expensive and for anyone struggling to spend that kind of money per month on their pup. Or those who are concerned with the drug's effect on the body long term, or those that are allergic. Advantix 2 has that added benefit of the mosquito repellent if you're religious in your re-applications.
So... yeah. You're going to see pictures of Poor Pink or Red skin. Statistically, there will ALWAYS be a % of animals that have an allergic reaction to inactive ingredients. However, as an owner of a dog with skin problems. Just be smart about spreading out the application and don't go putting detergents on your dog "washing it clean" because their skin got a little pink or irritated. THAT is what worsens the situation.
And I have gone through skin and fur issues with my pup to know this. My dog is allergic to the grass. I know skin irritation. Or should I say She Knows.
