your dog safe from irritating and dangerous pests with K9 Advantix II
for Large Dogs weighing 21-55 pounds. Formulated for dogs seven weeks of age and older and
weighing 21-55 pounds , K9 Advantix II outperforms its competitors
not only by killing more varieties of pests, but also by repelling them
to prevent future attacks.
Repels and Kills Ticks, Fleas, and Mosquitos
active ingredients in K9 Advantix II help keep your dog safe from
ticks, fleas, and mosquitoes. These effective compounds attack the
pests' nerve cells, paralyzing and effectively killing them, as well as
repelling them from future attacks. Most ticks are repelled and killed
before they can attach, which may reduce the risk of transmitting
disease-causing organisms to your pet. K9 Advantix II effectively kills
and repels Deer ticks, American dog ticks, Brown dog ticks, and Lone
Advantix II protects your pet against fleas at all stages of the
parasite's development. K9 Advantix II breaks the flea life cycle by
killing the living fleas on your dog before they can lay eggs. It also
prevents the development of existing flea eggs, larvae, and pupae,
helping to prevent future infestations.
Advantix II also kills reinfesting fleas (newly hatched fleas jumping
back on your dog) within two hours, and it prevents fleas on a treated
dog from infesting your home.
Effective Against Biting Flies and Lice
addition to complete tick, flea, and mosquito protection, K9 Advantix
II also repels painful biting flies from feeding on your dog, and it
effectively kills up to 100 percent of lice within one week of

has a bath or goes for a swim. Studies show that dogs are still
protected against parasites after exposure to water, though for best
results, dogs treated with K9 Advantix II should be bathed with a

is also important to protect indoor pets.

parasite, providing neurotoxic activity beyond that of each compound

much better with its target site.

Advantix II by Corrine from Cleveland Ohio03/20/2014
Best stuff on the market...protects your dogs from everything,,,and my dogs do not have a allergic reaction to this products like other ones...This is a little pricey, but worth it
Good Stuff by CJ10/25/2011
It seemed latley that all the different flea treatments quit working on my dogs. We tried K9 Advintix II and found it to work wonders. I especially like the fact that it controls fleas, ticks and mosquitoes.
Better than Frontline by carrolljung1 from Bennett Valley, CA10/12/2013
We have had a terrible flea problem where I live late summer and fall......Frontline was not working for my dog and for my neighbors' dogs as well. I switched to Advantix because we also have lots of ticks in the area (we live in rural Sonoma County CA) The Advantix has worked better....but our dogs still get fleas before a month on the dogs. Any suggestions????
by tdh from charlotte, nc03/13/2013
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.
great product by bandana from Bayboro, NC04/19/2013

Amazing Product by wfbanker from Wake Forest NC11/29/2012
I've tried many flea products and this is the ONLY one that got rid of my dog's fleas! They were gone the next day!
Excellent product by Brittany Guy from Puyallup, WA01/08/2013
Fleas just aren't a problem after using this product.
Great price, quick shipping. by Barry02/23/2012
Much better price than through local vets.
K9 Advantix II -- A good product. by Shirl from SE TX10/17/2013
After trying this product for the first time, I am glad I did. Put this product on some young dogs that were loaded with fleas. 24 hours later the fleas were gone! Would definitely recommend this product!
Great product by kellmar11/03/2012
I used to use Advantage for my dog, but then a friend recommended K9 Advantix and it really is a better product. It helps with much more than just fleas & ticks and protects my dog from other pests. I only purchase K9 Advantix through Entirely Pets...great customer service and fast delivery!
beware -- do your research by fawvekn10/22/2012
Within days of using flea drops on my dogs, one developed acute liver failure. Luckily, and many vet bills later, she is still alive. One month later, after reapplying drops, a second dog was diagnosed with acute lymphoblastic leukemia and probably will not survive more than a month. Do some internet research on flea drops, liver failure, leukemia, seizures, and paralysis. You will be shocked. I have used flea drops for years, but I will be looking for a more natural flea remedy after these two episodes.
by LM from Providence, RI10/23/2012
I have a cocker spaniel / retriever mix and this product works well. She's outdoors a lot and likes to swim.
Pleasantly surprised by Chieko from North Carolina08/20/2014
It really does repel small knats and flies.
Great product!! by Desiree from New York08/13/2013
I have been purchasing this product for years now and have never been disappointed!!
I am so glad i bought this by dot from State College, pa10/25/2012
Our groomer insisted i buy Advantix. I finally did and the results are impressive. First, this has no odor. We were using Certifect and the stink was awful.
And most importantly no ticks and we live in a heavily infested area.
So i say this is the best for preventing fleas and ticks ever!
no fleas by RNDirish from WV04/23/2012
My girls have never, knock on wood, had a flea problem while using this product.
Hopeful it works! by DM07/05/2012
We are hoping this product works better than the Frontline Plus we had been using. Our dog has been having a terrible problem with fleas this year due to such a mild winter. The other product has not been effective so we were told to try K9 Advantix II. So far so good for the month but it is still early. A change in product is recommended every so often to increase effectiveness--hope it works!!
The Best Product I have used by barb1934 from Atlanta GFa11/07/2012
Excellent results after a few days use. Easy to use.
Good Product at a great price by kellyjenne05/28/2012
We've used Advantix for our dogs for the last 5 years but always bought it from our vet. This year we go the same product from EntirelyPets but paid way less then we did from our vet.
Only use this product by Nancy R. from Sacramento, CA12/09/2012
I have used this product for a number of years for my dogs. I use the one for 21-55 lbs and the one for over 55 pounds. Since we have huge yard they play outside a big part of each day in all seasons. They have never had a flea or any other kind of bug. Since one of them is a Golden Retriever, fleas could be devastating. I am thankful for this product and for Entirely Pets.
K9 advantix II by JacKay from Edenton, NC08/22/2013
I have recently adopted a chow/golden mix from the animal shelter. The owners turned him in. He was using this flea and tick preventive when he was turned in. I have been pleased with this product although the vet I use stopped selling it because it was not giving adequate protection for sand fleas. We travel to go to this vet so we do not live on the beach. The product has been fine although he does do a little scratching but I am quite sure he is flea and tick free. We live around pine trees so ticks are very prevalent and I have not seen one on him.
Wonderful product by K32011/06/2012
Very effective product. Very happy with the results!!
by agriffin66 from Tifton,GA05/10/2013
Useless product. Opened it first so I could not return it. Product was o too small,My dog is 80 pounds! Your error not mine. Will buy elsewhere.
Wow! by Ellie Mae from Florida08/21/2013
We've been using another popular brand for years because it also treats for ticks. We live near a wooded area where ticks attack. This dog is unable to take internal flea meds due to pancreatitis and suffers terribly from the flea bites. So, just as horse owners rotate those wormers, it seemed that a change in flea meds couldn't hurt. Discovered that this product also treats for ticks and so we gave it a go. Our dog has now had three quiet weeks of seemingly flea free days and nights.
On the down side, it is oily and our dog has silky hair so the oil spreads out and looks terrible until we can bath him.
Also, we no longer have a vibrator on our bed...
love it by Diane from Sidney, Ohio02/21/2013
This product is great no more fleas or ticks.
It worked by Angie11/13/2013
I had used frontline for years, and then my dogs got fleas. All 4 of them. I tried everything, from knockout spray, flea dips, flea combs, frontline spray, bought a carpet shampooer, diatamacious earth, nothing helped. I vacuumed every day, and washed every sheet blanket, slipcover in the house every 2 days. After I applied the advantic I saw an 80% improvement within a day.
I have used K9 ADVANTIX in the past and like the product. I use it each month including the winter months. I will continue to buy the product
Better than Frontline by Amy H from Richmond,VA11/23/2012
This summer I had serious issues with fleas to the extent that we had our yard treated. The Frontline Plus wasn't touching the problem. I switched to k9 advantix II and noticed a difference immediately.
Good Product by Jim from AL06/12/2014
I recommend this product and would purchase again.
Another quality product by Al from Pewaukee, WI06/24/2012
I've always had good results from anything I've ordered from Entirely Pets and I will continue to patronize this site.
Great on fleas & ticks by Aspen pup from Los Gatos, CA03/26/2012
Love this product, much more effective than Frontline.
K9 Advantix by BeagleBoy10/12/2013
I've used this product for the past 4 yrs and my dog has never had fleas or ticks so I'm assuming this product is very effective. Its easy to use and is very affordable.
very good product by barbie from Parsippany, NJ07/17/2013
K9 Advantix is the best product to keep mosquitos away from your dog. Mosquitos are more attracted to light or white color dogs. This was my first time using this product and not one bite since, and this year its a bad season.
K9 AdvantixII by KinPA from Stroudsburg, PA07/06/2012
Love this product. Love the fact my dog does not get fleas on his body at all. I love Entirely Pets. Great bargains all the time. thank you.
