  • 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.

She goes a little crazy for about 2 minutes when she first gets it on her but that is all. It really keeps the fleas ticks and mosquitos off.

Great value and works great
I switched from Frontline plus to K9 Advantix because we were still finding fleas while using Frontline. Since the change we have had no problems with fleas or ticks. I also like that it repels mosquitos which can help protect your pet from mosquitos that are infected with heartworm.

ticks dont die
The wood ticks dont die and fall off. They stay stuck and when you take them off they are still alive. It doesnt seem to repel the ticks either.

Review for 4 MONTH K9 Advantix II TEAL for Medium Dogs (11-20 lbs)
A friend of mine recommended this product after having tried several others. I decided to not waste my money doing the same thing and have been ordering this for 1.5 years. We have 2 dogs and in that time I have only seen 1 flea on one dog. However, I have had a few bite me and my indoor cats keep getting fleas.

Mosquito protection for the summer
We use both Frontline and Advantix products for flea and tick prevention, but switch to the Advantix during our humid summers when mosquitoes are plentiful. Our dog has allergies and sensitive skin, but has not had any adverse reactions to the Advantix.

As a single parent to my Bichon, times are tough, but I don't want to compromise her health care. Entirely Pets along with Groupon made it possible for me to continue to keep Maggie protected against fleas, ticks, and the disease they carry.

Worth Every Penny
Our 3 dogs never have a bug - ever! Many of my friends/neighbors are upset that in spite of using flea/tick control products their animals still get fleas and ticks. Our dogs have never (thank God) gotten a bug on them. We recommend this product to everyone.
