K9 Advantix ^® Flea & Tick Control Treatment for Dogs

Dr. Foster & Dr. Smith don't compromise on what they use for a monthly topical flea and tick treatment for dogs - that's why they only use K9 Advantix on their own dogs. They feel that K9 Advantix offers the best advantage for flea and tick protection available, and recommend this effective monthly flea & tick topical to their clients. K9 Advantix is manufactured by the Bayer Corp., a trusted and dedicated name in animal healthcare. For dogs only: 7 weeks or older.

How to apply:
Step 1
The dog should be standing for easy application. Part the hair at your dog's shoulder blades to expose the skin.
Step 2
Apply product evenly and directly to the skin in three or four spots along the dog's back by squeezing out the tube's contents.(For dogs 20 lbs. or less, apply on one spot.)
Step 3
Be sure to empty the entire tube by the end of the application. Your dog's natural movements will help spread K9 Advantix over the skin.

What makes Advantix Special?

Synergistic Effect
The two active ingredients imidacloprid and permethrin are often used alone as effective treatments against parasites. However, the combination Advantix formula works synergistically to provide more protection than each of these ingredients alone. Together, they complement one another to enhance their effectiveness and provide complete protection against fleas, ticks, and mosquitoes.

The active ingredient imidacloprid is an EPA approved topical insecticide that kills adult fleas by disrupting their nervous system. Fleas in their larval stages are also killed when they come in contact with the treated pet or their immediate surroundings. Permethrin is a synthetic pyrethrin compound commonly used to kill flying insects, fleas, and ticks. EPA approved for use in dogs, permethrin affects the nervous system of parasites, causing repetitive nerve firings that eventually paralyze and kill them. Permethrin is longer lasting and more stable than natural pyrethrin. For this reason, it is commonly found in repellents, premise sprays, and in products intended for slower, but sustained action. K9 Advantix takes advantage of these properties to offer superior protection against fleas, ticks, and mosquitoes.

Protection Against Fleas
K9 Advantix stops fleas from biting in less than 5 minutes and kills 98-100% of fleas on your dog within 12 hours of application. Advantix kills fleas before they have a chance to lay eggs and also kills flea larva before they develop into biting fleas - thus breaking the flea life cycle. Re-infesting fleas are killed within 2 hours for reliable treatment against fleas of all stages. In many instances Advantix is so effective, it kills fleas before they have a chance to bite your pet, preventing conditions such as Flea Allergy Dermatitis.

Protection Against Ticks
K9 Advantix repels and kills Deer ticks, American dog ticks, Lone Star ticks, and Brown dog ticks before they can latch onto your pet. It repels up to 98% of ticks to dramatically reduce disease spread by ticks.

Protection Against Mosquitoes
K9 Advantix repels and kills mosquitoes before they can bite and needless to say, mosquitoes that don't bite can't annoy dogs or transmit disease. Research demonstrates K9 Advantix kills up to 98.3% of mosquitoes and reduces their feeding up to 95.2%.

Water-resistant Formula
K9 Advantix remains effective after swimming or bathing. Even after repeated swims, or bathing it remains an effective treatment.

Easy Application
Advantix is a monthly topical treatment that is easily applied between your pet's shoulder blades. One application stop fleas from biting in 3 to 5 minutes and is gentle enough for puppies (7 weeks or older) and dogs of all sizes.

I switched vets last year. She didn't have Frontline. So she recommended ADVANTIX for my two Boston Terriers. It killed their ticks and I haven't had a problem since. I love it.

K9 Advantix is by far the #1 Flea & Tick control for dogs, I've seen and used. We've been using K9 Advantix since we got DELILAH our Labrador Retriever, 3 -1/2 years ago. Don't plan on stopping either. Fleas, Ticks, and Mosquitoes not a problem, and she loves the water. You love your dog, get the best, I recommend K9 Advantix.

I would recommend K9 Advantix to any dog lover. Having tried other products - they failed or only worked for a week or two. With K9 Advantix, I wait 30 days; NO FLEAS; even wait a week longer! Still NO FLEAS! NO SCRATCHING. My Yorkie-Poos love it and so will you! Also love the TV ad!

Last year I tried K9 Advantix for the first time after my previous brand failed to repel fleas. Even though it is more expensive, it is worth every penny. Within one day of applying it, the fleas were dead and gone. No more problems the rest of that year and none so far this year. The fact that it also takes care of mosquitos is frosting on the cake. Tremendous product.

I have a Siberian Husky. I use to use Frontline Plus and she still use to get ticks on her. I ordered K9 Advantix as per the Doctors Choice and I put it on my Husky. It works well. My Husky and I walk in the woods and I check her for ticks and fleas all the time, I don't ever see any ticks and fleas, thanks. K9 Advantix is the best flea and tick product I ever received. I love the product, thanks again.

This is the only product I have ever used on my dog. I highly recommend it to everyone. He has never had a flea or tick and is never bothered by mosquitoes when we are outside. I wish I was that lucky. I also recommend it to all my clients after their grooming sessions. It is well worth the little extra you pay for all the protection you get.

I just wanted to share with you that I have tried Frontline Plus as my vet suggested and found fleas on my dog and then I found a tick on me. I was looking for an alternative product and found in your catalogs and on your website K-9 Avantix that your veterinarians recommended and use on their own dogs. I have not since had trouble with fleas or ticks. Thanks.

I have tried other topicals in the past but K9 Advantix is the best by far!! I have 5 dogs and live on the edge of the woods and water. Since I started using Advantix I am not only finding no ticks on my dogs but I have not seen ANY in the house!! It is easy to use and does not damage the dogs coat (very inportant as I have show dogs) and it works!

I live in Florida where flea season lasts from 10-12 months a year. I used a recommended and popular brand of "bath proof" flea and tick control on my mini Dachshund and was quite disappointed when she had fleas a week later. I switched to K9 Advantix and I've been thrilled with the results. It absorbs quickly and doesn't leave an oily residue on her fur. I haven't seen one flea on her and she gets bathed twice a month. Foster and Smith offers great prices on products and shipping. Even ordering prescription products is quick and easy.

The cheapest price is here and it saves money in my pocket. I love K9 Advantix and it's the only flea and tick medication I trust in the south. During the summer months fleas and ticks are always around and since I live in the woods it doesn't make it better. I've never seen a flea or tick on my dog ever and I'm truly happy about that.

I love K9 Advantix. I have tried other flea products and none work as well. I have a Collie that has flea allergies and none of the other products would help. It has been a wonderful summer without all the problems. Now I use Advantix on all my dogs! I love the fact that it repels fleas, ticks, and mosquitos as well. Because we travel with our show dogs Advantix seemed to be the best fit due to different conditions within each state. I am hooked!

I have 3 large dogs and live in a wooded area. I had used another tick/flea medication and my dogs ended up with ticks despite that medication and a Lyme disease vacination. A few years ago, my vet recommended K9 Advantix and since then my dogs have not had a single tick. I had purchased this from 1-800-petmeds but the huge savings (almost $30.00) is needed from Drs. Fosters & Smith with three large dogs. Way to go, quality and a great price. I tell all my local pet lovers of this site so they can save on K9 too.

I used to have to try everything just to keep my dogs flea free. Now I don't even have to give them flea medicated shampoo. It's so easy too, it even works when my dogs have been outside where we have horses. I woud recommend K9 Advantix to anyone with flea problems.

We live in an area that is heavily infested with mosquitoes in the summer months. I have used K9 Advantix since it came out on the market. We first heard about it from an advertisement during the Westminster Kennel Club Show a few years ago. My dogs have a much more comfortable summer because the mosquitoes are no longer attacking them.

Our son surprised us with a 7-1/2 month old Beagle puppy, Dusty. I didn't check him for a couple of days, but when I did I saw he had fleas! I immediately got out the K9 Advantix and treated all of the pets. After the initial treatment, I never saw another flea. What a great product!

I have 5 dogs and I have to say this product is the best. I have seen neither flea nor tick all summer, and even though I skip a month or so in fall/winter no fleas have returned. I would highly recommend it to anyone.

Last year I used another top name product. This year I used K9 Advantix and now I will never use anything else. That says it all!

I am using this on five dogs and it works great. It is much easier to control the fleas than other methods and I live in Texas so there is a large population of mosquitoes. I have an allergic dog so I don't want anything to bite him and so far so good. I have been using it two months now and it is far easier than worrying about when the dogs are out at the same time the mosquitoes are.

Jo Ann W

K9 Advantix is working very well on my Great Danes. I live right next to a lake, so there is always standing water for mosquitoes to breed, and lots of trees and wildlife, and we constantly have to guard against fleas and ticks. Thank goodness we found K9 Advantix!

Debbie W

My veterinarian highly recommends using K9 Advantix. My Chihuahua has a lot of allergies to fleas and so he recommends using this instead of the other monthly topicals. Last year I was using another topical product and my dog ended up pulling his hair out, but after we started using K9 Advantix I have not had that problem at all. I love it, it is so easy to use and it works great. I couldn't be happier!

Beverly R

I own a grooming business and use only K9 Advantix. I have 4 dogs of my own and live out in the country. I have never found a tick or flea on any of my dogs. I love the product and tell everyone that it's a great buy at Foster & Smith. I know a good deal when I see one. It's a win-win situation. Thanks!

Amazing product. I've used Frontline before and found fleas on my dogs. She was also scratching so much. Then I saw the K9 Advantix commercial on TV and tried the product. It's worth every penny. My dog doesn't scratch anymore and I don't see any fleas on her at all. Would recommend it to all dog owners.

I have used K9 Advantix for many years. With my first dog I did try another brand. She broke out in a bad rash. We went to the vet and discovered she was allergic to that brand. Our Vet suggested we try K9 Advantix, we did. We have now used K9 for all our dogs. I just lost my first one or 15 yrs. Then aquired three more of God's angels. Go K9 Advantix.

Cosmo, my Jack Russell Terrier, has been using K9 Advantix since I became his mommy. This so far has been the best product I have ever used. With my other dog, I used Bio Spot and Frontline and they worked for about 2 weeks tops. With K9 Advantix my Cosmo has been flea and tick free throughout last summer into the fall. I just placed an order and it came here today. I am very pleased with Drs. Foster and Smith and their customer service.

I had always used K9 Advantix on my Flat Coat Retriever. This spring my vet said they had switched over to Frontline and were not offering K9. I bought the Frontline and what problems we have had with fleas! I ended up having to spend extra money for a cortisone shot because my dog is allergic to flea bites. Also had to buy pills to kill the fleas on her and buy a product to treat my yard - all at the vet's direction. Well, she still had fleas and I even found a few bites on my kids! Needless to say she is back on K9 which I ordered online and we are all doing much better. Buying a lower priced product didn't save us any money. Pay a little more for K9 and you will not have to spend more money fighting fleas. You will also save your beloved pet so much misery. I will never use anything other than K9 Advantix.

This is by far the best product on the market. I tried to save money by using the less expensive, and it did not work! It was a nightmare! Since using Advantix, no more worries, and vet bills caused by allergic problems associated with fleas with my pug.

I have 5 dogs and living in Florida has been a challenge with ticks and fleas. I was using another product with poor results and my groomer recommended K9 Advantix. We are so pleased with the results of this product and our dogs are happier campers also.
