This product promises to kill and repel ticks, fleas, and mosquitoes. Its waterproof formulation remains effective even after the pet gets wet. The K9 Advantix II solution works by attacking all the life stages of the parasites killing adult bugs, larvae, and eggs. The K9 Advantix II Teal is a specialized product for medium dogs weighing 11 to 20 lbs. This particular pack contains 4 doses, which is good for 4 months of protection against ticks and fleas.

  • For medium dogs weighing 11-20 lbs
  • Manufactured by Bayer
  • Waterproof formulation
  • Repels ticks, fleas and mosquitoes
  • Kill parasites of all life stages
  • For dogs only


Imidacloprid: Imidacloprid is an ectoparasiticide, an antiparasitic agent that targets parasites living primarily on the surface of a host. Chemically classified as a chloronicotinyl nitroguanidine, imidacloprid inhibits neurotransmitter transmission in insects, resulting in paralysis and death.

Benefits: Imidacloprid exhibits both adulticide and larvicidal flea efficacy; it not only kills adult fleas and larvae on your pet, but it also kills larval stages in your pet's immediate surroundings.

Main Purpose: To kill fleas at all stages of their life cycles and stop them from being able to move or feed.

Permethrin: Permethrin is the additional ingredient in Advantix. It belongs to the Type I class of pyrethroid acaricides and insecticides, and it also acts as a repellent. Pyrethroids affect muscle and nerve cells' sodium ion channels by increasing their mean open time, which leads to hyperexcitability and death of the parasite.

Benefits: Thanks to its repelling activity, permethrin reduces parasite bites and thus the risk of diseases and stress for your dog.

Main Purpose: To repel ticks, sand flies, and mosquitoes; to kill ticks and fleas.

Two Proven Ingredients with Enhanced Activity: Imidacloprid and permethrin work together to overwhelm the nervous system of the parasite, providing neurotoxic activity beyond that of each compound alone. This leads to more profound and quicker insect paralysis and death.

Specifically, imidacloprid increases the efficacy of permethrin by activating insect nerve cells and increasing the frequency of neurotransmissions. As a result, more sodium channels are opened and the pyrethroid can interact much better with its target site.

Pyriproxyfen: Pyriproxyfen is a pyridine-based pesticide. A juvenile hormone analog, it interferes with the hormone signaling of growing insects, so that insects in immature stages are unable to mature. Additionally, a female insect that touches the toxin will produce eggs that will not hatch.

Benefits: Pyriproxyfen provides an added layer of protection for pets and their surroundings. It interrupts the flea life cycle at multiple stages, halting the growth and development of insect eggs and larvae and preventing re-infestation.

Main Purpose: To prevent flea eggs from hatching and larvae from growing.

Useful Information

Applying K9 Advantix II to your pet is a fast and easy process. First, remove the K9 Advantix II applicator tube from its packaging and use scissors to peel down the foil. Next, hold the applicator tube in an upright position and pull the cap off the tube. Use the upturned cap to break the protective seal, and you're ready for application.

For easiest application, your dog should be standing upright. Evenly apply the entire contents of the K9 Advantix II tube to two or three spots from the back of the shoulder to the base of the tail. Part the hair at each spot until the skin is visible, then place the tip of the tube on the skin and gently squeeze out a portion of the solution. Be careful not to apply an excessive amount of the solution in any one spot, otherwise some of the solution might run off the side of your dog. Dispose of the container and do not reuse or refill. Do not empty unused product in any indoor or outdoor drain.

For optimal control and prevention of parasites, use K9 Advantix II every month. K9 Advantix II is available in four- and six-month supplies. Do not use K9 Advantix II on cats or any animals other than dogs.

Application Instructions: Evenly apply the entire contents of the tube to four to six spots on the top of the back--from the shoulder to the base of the tail. Apply monthly.

Length of Effectiveness: Under normal conditions, the product is effective for one month. However, in cases of severe flea infestation, re-treatment may be necessary earlier than four weeks. Do not retreat more often than once every seven days. After flea control is attained, return to a monthly re-treatment schedule.

Always quality
I have been using K9 Advantix for years. I live in Georgia (bug state of the world) and have three daschunds (low bellys). This flea and tick medication works great. Entirely Pets have always had fair prices and great, fast shipping.

Great Product
I have tried many flea and tick products over the years but K9 Advantix II is the best by far. I have three indoor dogs that sleep on the bed and are all over my home and furniture. This product works so well as long as you keep up with using it monthly. My dogs are not scratching and we are not dealing with fleas. It covers all the bases with fleas, ticks, and mosquitoes. My dogs are happy and that makes mama happy!

Review for 6 MONTH K9 Advantix II TEAL for Medium Dogs (11-20 lbs)

Atlanta Mom Dissapointed
I have two shih tzus with short hair because I keep them trimmed so I can see the ticks. I do not have them bathed a week before or a week after I apply it. This does not stop the ticks at all. Every day I pull 2-3 engorged ticks off of them. Frontline does not work and neither does this. I don't know what to try next. They only go outside maybe 4 times a day for 5 min.

K9 Advantix II
I have used this product for many years. I have three young doxies that love to run and play in the yard for hours. I live in Georgia and the fleas and ticks are terrible here. We find ticks on the dogs, they are usually dead and fall off. This product works better than any other I have tried.

Works Well
The k9 advantix II works well for my dogs. The fleas are minimal and we have not had major issues this season. It has worked great for our dogs.

Product works well with Trifexis
My allergic dog cannot take Heartguard for heartworms because the med is contained in a beef base, so he has to take Trifexis, which also contains a flea med. Since Lymes Disease is rampant in this part of Virginia, we must apply a tick preventative as well. K9 Advantage II provides the necessary tick control, but its flea med does not cause an overdose with that in Trifexis. The mosquito protection is also nice during our humid summers. The product is less greasy than the new Activyl.

Working as Advertized
This product is working as advertized!
Great to know that have some protection for the dog til November from tics & fleas.Have seen a mosquito yet mosquito biting season has yet to start.So do not know how it will work when they start biting.
Although pricy,any dog deserves good protection!
In fact would've given 5 star rating if not for being so pricy..Although thankx to "Entirely Pets" received a discount.

Kills Deer Ticks
and is also, I believe, registered as a mosquito repellant. Where, I live, in NW VT, these are the primary insectival parasites. This past summer was -- I was told by others -- a terrible years for deer ticks in my area. But I found only one .... on myself, not my dog.

I think this is a great product, and have been using it -- according to the directions (which is important to remember) for many years.

Very good product at a good price
K9 Advantix seems to work very well on my sheltie, even in South Florida, which is a nightmare of bugs! Other products do not work well here. Entirely Pets usually has the best price for this product.
