Been buying and using this product every month from 1800Petmeds.com since 2008 when Sophie was 4 months old. She is now 13 years old and has NEVER had a flea or tick since. I love that we get free shipping and a 10-20% discount every time I buy a new box. Thank you 1800petmeds.com!

Great Stuff
My husband and I have been using K9 Advantix 11 on our dogs for over 20 years. We are and always have been pleased with the protection our dogs receive. Their groomer always comments that she never sees any pests on any of them. For our furbabies, this product is totally worth the money.

Misrepresentation and over priced items.
In the past, I have always bought Avantix II for my dog, Karl. Someone has to talk to the biochemist and tell them to use the old product. There's definitely a change in the product. It cost me over $200.00 Canadian, without avail, and me as a consumer, couldn't believe that the product was watered down in order to meet for the bottom line in accounting. I have used this product time and time again and I had no problems with the product. This time, I used 8 vials and nothing worked on my dog. It was a total waste of money and time. And the only one that's suffering is my dog. Take it off of the market. Never will I trust any of these products and my faith is quickly going down the path of distrust. I don't enjoy giving you a bad decision mark, but my back is against the wall.

After coming across this one and done product many years ago(after trying flea collars, tick stuff & mosquito repellent) I will never use anything else. Its quick and easy to apply & doesn't have any side effects. It has a repellent for fleas and ticks so the bugs don't go on them. If by chance they do jump on they will be killed on first bite. GREAT STUFF!!

K9 Advantix II
I purchased this product for my dogs and it did not work. I called customer service and they told me that it had to be used for 3 months before the product would get rid of the fleas. My dogs are inside dogs and only go out to play and potty so they are not living outdoors with the flea population. If you have to use it for 3 months before it works what is the point except for them to be able to sell more product.

QUESTION
can you give your dog a bath one day after applying K9 Advantix
ANSWERS (1)
Thank you for your question. As a general rule of thumb, when applying any spot-on, topical, or at times even oral medication to your pet, it is best to wait at least 48 hours before bathing. In the case of flea and tick prevention, this allows the product to begin working effectively.

What is K9 Advantix II?

K9 Advantix II is a monthly preventative for dogs that offers comprehensive protection against ticks, fleas, mosquitoes, biting flies, and chewing lice. K9 Advantix II is a top veterinarian-recommended brand because it repels and kills all life stages of fleas (eggs, pupae, larvae, and adult fleas) and ticks (Deer ticks, American dog ticks, Brown dog ticks, and Lone Star ticks). K9 Advantix II kills 98-100 percent of fleas within 12 hours and continues working for one month to prevent infestations. Fleas and ticks are killed on contact with a treated dog, which means that fleas don't have to bite and ticks don't have to attach to die. This helps prevent transmission of flea-borne and tick-borne diseases such as tapeworms, Lyme disease, tick paralysis, ehrlichia, and Rocky Mountain spotted fever. Killing fleas before they bite may also help prevent skin allergies caused by flea saliva. As well, K9 Advantix II repels mosquitoes before they bite, which may help prevent transmission of heartworms. K9 Advantix II protects your pet before parasites have a chance to bite, not after.

For:

Dogs and Puppies (7+ weeks of age, weighing 4+ lbs)

Benefits:

  • Repels and kills disease-carrying fleas, ticks, and mosquitoes before they bite
  • Kills all life stages of fleas (eggs, pupae, larvae, and adult fleas) and ticks (Deer ticks, American dog ticks, Brown dog ticks, and Lone Star ticks)
  • Kills 98-100 percent of adult fleas within 12 hours
  • Ends flea life cycle by preventing flea offspring (eggs, pupae, and larvae) from maturing into adult fleas
  • Repels biting flies and kills chewing lice
  • Provides one month of protection against ticks, fleas, mosquitoes, biting flies
  • Waterproof - remains effective following a shampoo treatment, swimming or after exposure to rain or sunlight

How does K9 Advantix II work?

K9 Advantix II combines imidacloprid and permethrin to repel and kill fleas, ticks, and mosquitoes. Both ingredients work on contact, attacking parasite nerve cells at different sites. Together these ingredients overwhelm the nervous system killing the parasite. Pyriproxyfen is an insect growth regulator. K9 Advantix II topical solution also repels biting flies and kills lice.

Cautions:

DO NOT USE ON CATS. Cats cannot metabolize the ingredients used in this product. Cats must be separated from dogs during treatment. Do not allow your cat to come in contact with a treated dog for 24 hours. Some small and medium dogs may have an adverse skin reaction.

Brand Name:

K9 Advantix II (Bayer)

What is the most important thing I should know about K9 Advantix II?

The active ingredients in K9 Advantix II are Imidacloprid (8.8%), Permethrin (44.0%), and Pyriproxyfen (0.44%). K9 Advantix II is for use on dogs and puppies weighing 4 lbs or more and 7 weeks of age or older. It is used for the topical prevention and treatment of ticks, fleas, mosquitoes, biting flies, and chewing lice on dogs. K9 Advantix II repels and kills ticks including deer ticks (the major carrier of Lyme disease), American dog ticks, Brown dog ticks and lone star ticks. Additionally, K9 Advantix II repels and kills all life stages of fleas, repels and kills mosquitoes, kills chewing lice, and repels biting flies. K9 Advantix II is a non-prescription (OTC) product available as 0.014 fl oz (0.4 ml) applicators for dogs 4-10 lbs (Green), 0.034 fl oz (1.0 ml) applicators for dogs 11-20 lbs (Teal), 0.084 fl oz (2.5 ml) applicators for dogs 21-55 lbs (Red), and 0.135 fl oz (4.0 ml) applicators for dogs over 55 lbs (Blue).

What should I discuss with my veterinarian before giving K9 Advantix II to my pet?

Consult a veterinarian before using on medicated animals and debilitated, aged, pregnant or nursing animals.

How should K9 Advantix II be applied?

For use only on dogs. Do not use on cats or on other animals. Have your dog stand for easy application. Part the hair on your dog's back between the shoulder blades, until the skin is visible. For dogs up to 20 lbs, apply the entire contents of the applicator tube to 2 or 3 spots on the top of the back from the shoulder to the base of the tail. For dogs 21 lbs and over, apply the entire contents of the applicator tube to 4 or 6 spots on the top of the back from the shoulder to the base of the tail. If your household has cats or other pets, separate them from the treated dog for 24 hours.

What are the potential side effects of K9 Advantix II?

Monitor your dog after application. Side effects may include signs of skin irritation such as redness, scratching, or other signs of discomfort. Gastrointestinal signs such as vomiting or diarrhea have also been reported. If these or other side effects (such as lethargy or agitation) occur, consult your veterinarian or call 1-800-422-9874. Individual sensitivities, while rare, may occur after using any pesticide product for pets. A small percentage of dogs have had adverse reactions to K9 Advantix II. A sensation of burning, tingling, itching, redness or numbness of the skin may occur after topical application. This sensation usually begins 1-2 hours after application. In addition, reactions have occurred in cats that have been exposed to a medicated dog. That is why it is important to separate your cat from a medicated dog for 24 hours. Bayer, the manufacturer of K9 Advantix II, indicates that some of these symptoms will dissipate within 48 hours; however, if your pet is experiencing adverse reactions, please complete the following steps:

  • Stop applying the medication
  • Wash your dog with a detergent based soap (Dawn or Palmolive dish detergents work best). Do not scrub the affected area, as this may cause more skin irritation. Please note: This process is applicable for both dogs and cats.
  • Call your veterinarian
  • Call Bayer Emergency Support Line at 1-800-422-9874. Let Bayer know your dog is having an adverse reaction to K9 Advantix by calling 1-800-422-9874. This line is staffed 24 hours a day, 7 days a week.

What happens if I miss giving a dose of K9 Advantix II?

If you miss a dose, apply the next dose as soon as possible and resume a monthly schedule.

What happens if I overdose my pet on K9 Advantix II?

Contact your veterinarian or veterinary emergency room.

What should I avoid while giving K9 Advantix II to my pet?

It is important to apply this product no more than once a month and to use the correct strength for the weight of the dog. This product is harmful to humans if swallowed.

Been buying and using this product every month from 1800Petmeds.com since 2008 when Sophie was 4 months old. She is now 13 years old and has NEVER had a flea or tick since. I love that we get free shipping and a 10-20% discount every time I buy a new box. Thank you 1800petmeds.com!

Great Stuff
My husband and I have been using K9 Advantix 11 on our dogs for over 20 years. We are and always have been pleased with the protection our dogs receive. Their groomer always comments that she never sees any pests on any of them. For our furbabies, this product is totally worth the money.

Misrepresentation and over priced items.
In the past, I have always bought Avantix II for my dog, Karl. Someone has to talk to the biochemist and tell them to use the old product. There's definitely a change in the product. It cost me over $200.00 Canadian, without avail, and me as a consumer, couldn't believe that the product was watered down in order to meet for the bottom line in accounting. I have used this product time and time again and I had no problems with the product. This time, I used 8 vials and nothing worked on my dog. It was a total waste of money and time. And the only one that's suffering is my dog. Take it off of the market. Never will I trust any of these products and my faith is quickly going down the path of distrust. I don't enjoy giving you a bad decision mark, but my back is against the wall.

Highly Recommended!!
After coming across this one and done product many years ago(after trying flea collars, tick stuff & mosquito repellent) I will never use anything else. Its quick and easy to apply & doesn't have any side effects. It has a repellent for fleas and ticks so the bugs don't go on them. If by chance they do jump on they will be killed on first bite. GREAT STUFF!!

K9 Advantix II
I purchased this product for my dogs and it did not work. I called customer service and they told me that it had to be used for 3 months before the product would get rid of the fleas. My dogs are inside dogs and only go out to play and potty so they are not living outdoors with the flea population. If you have to use it for 3 months before it works what is the point except for them to be able to sell more product.

QUESTION
can you give your dog a bath one day after applying K9 Advantix
ANSWERS (1)
Thank you for your question. As a general rule of thumb, when applying any spot-on, topical, or at times even oral medication to your pet, it is best to wait at least 48 hours before bathing. In the case of flea and tick prevention, this allows the product to begin working effectively.
