General Product Information
K9 Advantix is a preventive medication for dogs that is intended for monthly administration. The primary purpose of K9 Advantix is to repel and kill fleas and ticks as well as mosquitoes. Due to its repellent and killing effects, K9 Advantix offers broader spectrum protection against infestation than other similar brands on the market. According to the manufacturer, K9 Advantix will prevent fleas from biting in as little as five minutes, with up to 100% of these pests being completely eradicated in as little as 12 hours.
K9 Advantix is intended for use in dogs seven weeks old and older.
The manufacturer also claims that K9 Advantix can eliminate virtually all flea larvae in less than 20 minutes, and will repel mosquitoes before they can even bite your pet. In addition, K9 Advantix will continue to work even after giving your pet a bath.
The primary ingredients in K9 Advantix are Imidacloprid and Permethrin, both of which in combination effectively eliminate fleas, ticks, and mosquitoes. These ingredients will immediately have an effect on the aforementioned pests upon contact, attacking and overwhelming their nervous system and eventually leading to paralysis and death.
K9 Advantix is manufactured by Bayer, and is available in packages of 4, 6, 12 doses.
Possible Side Effects As Acknowledged By The Manufacturer

K9 Advantix
According to the manufacturer, pets that are treated with K9 Advantix may experience burning and/or itching on the area where the medication is applied. In some cases, there may also be a tingling sensation, which may or may not be accompanied by numbness. These effects are commonly experienced one to two hours after K9 Advantix is applied, and they will generally disappear in one to three days. Using a gentle dog shampoo on your pet will hasten the recovery process and make these side effects disappear much more quickly.
As with all types of medications, it would be best to consult your veterinarian before using K9 Advantix on dogs that are undergoing treatment with some other types of medication. This also goes for dogs that are injured, pregnant, or lactating, as well as older dogs. Under no circumstances should you use K9 Advantix more then once a month on your pet. It is also important to make sure that you use the proper concentration of the solution depending on the weight of your pet.
Customer Reviews And Ratings
Customer reviews on K9 Advantix appear to be largely positive. One customer has reported using several different anti-flea medications on her dog with very little appreciable results. After switching to K9 Advantix however, her dog’s condition rapidly improved, and he has remained largely free from infestation for several months.
One other customer reports of a sudden flea infestation after several months of her dog being pest free. The sudden flea infestation was particularly alarming, since her dog turned out to be allergic to the fleas. This customer’s dog developed scabs throughout his body and began rapidly shedding hair in several spots. It only took two days of treatment with K9 Advantix however, before all the signs of itchiness disappeared, and her dog’s coat started to clear up. After several weeks of use, this customer’s dog was completely back to normal with the same luxurious coat that he had prior to infestation, and was noticeably healthier and happier besides.
Finally, one other user reported using K9 Advantix on both a Labrador and a German Shepherd for several years, experiencing generally satisfactory results. After ceasing treatment for several weeks however, both dogs rapidly developed a severe flea infestation. In spite of the severity of the attack, only a few days of treatment with K9 Advantix was enough to cause the fleas to retreat, and both dogs have been healthy ever since.
This stuff does NOT work worth a damn I recently visited a friend that lives in the country in Alabama, when I returned home I gave my cocker a bath and a haircut. With all the hair gone I found well over a 100 ticks in her. I called the manufacturer, and the lady I talked to thought a 100 was no big deal and asked in a very smart ass attitude well what do you expect us to do! I said absolutely nothing!
Also I left a bad review on petsmart and petco and they didn’t post the review they both hide most of the bad ones so their customers don’t see them, which I find dishonest.In fact I am beginning to believe most reviews on everything are fake. But as far as K9 advantix it DOES NOT WORK!!! Save you money!
