Description

Help protect your gentle giant from parasitic pests and the potentially harmful diseases they can transmit with K9 Advantix II Flea & Tick Treatment for Extra Large Dogs. This broad-spectrum, veterinarian-recommended treatment is specifically formulated to repel and kill fleas, ticks and mosquitoes on contact with no painful biting required. It further kills all life stages of fleas to prevent re-infestation, and even kills lice while also repelling biting flies. The waterproof formula for puppies and dogs 7 weeks or older and weighing 55 pounds or more continues working for up to four weeks, even after bathing or swimming.

Key Benefits

  • Broad-spectrum, veterinarian-recommended treatment repels and kills fleas, ticks and mosquitoes on dogs 7 weeks or older and weighing 55 pounds or more.
  • Begins working within 12 hours and kills pests on contact.
  • Kills all life stages of fleas to prevent re-infestation; also kills lice and even repels biting flies.
  • Waterproof formula continues working for up to four weeks, even after bathing or swimming.
  • Convenient, monthly topical application contains imidacloprid, permethrin and pyriproxyfen; available in packs of 2, 4 or 6 treatments.

Precautions

USE ONLY ON DOGS AND PUPPIES 7 WEEKS OF AGE AND OLDER AND WEIGHING 55 LBS. OR MORE. DO NOT USE ON CATS. Do not get this product in dog’s eyes or mouth. As with any product, consult your veterinarian before using this product on debilitated, aged, pregnant or nursing animals. Individual sensitivities, while rate, may occur after using ANY pesticide product on dogs. If signs persist, or become severe, consult a veterinarian immediately. If your animal is on medication, consult your veterinarian before using this or any other product. Keep out of reach of children.

Important Information

Fleas rise to the top of your pet’s coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

Ingredients

Active Ingredients: Imidacloprid 8.80%, Permethrin 44.00%, Pyriproxyfen 0.44%.

Instructions

How to open:

  • Be sure tube is at bottom of pouch.
  • Using scissors, cut the pouch across the top and remove tube.

How to apply:

  • Use only on dogs.
  • Remove applicator tube from the package. Use scissors and peel down foil.
  • Hold applicator tube in an upright position. Pull cap off tube.
  • Turn the cap around and place other end of cap back on tube.
  • Twist cap to break seal, then remove cap from tube.
  • The dog should be standing for easy application. The entire contents of the K9 Advantix II tube should be applied evenly on the top of the back from the shoulder to the base of the tail. At each spot, part the hair until the skin is visible. Place the tip of the tube on the skin and gently squeeze to expel a portion of the solution on the skin. Do not apply an excessive amount of solution at any one spot that could cause some of the solution to run off the side of the dog.
  • Discard empty tube.
  • In cases of severe pest infestations, retreatment is allowable earlier than 4 weeks. Do not retreat more often than once every 7 days. After pest control is attained, return to a monthly retreatment schedule.

Experience the Advantages of K9 Advantix II

Veterinarian-recommended K9 Advantix II kills fleas, ticks, mosquitoes and lice, and repels biting flies. Now you can help your dog fight these pesky pests through contact—no biting required. Convenient and easy to use, K9 Advantix II is for dogs and puppies 7 weeks of age or older. So help your pal get the effective protection he needs with all of the advantages of K9 Advantix II.

Why are Biting Bugs a Big Deal?

K9 Advantix II spreads over the skin and hair to kill and repel them through contact, meaning they do not have to bite to die. And if a flea, tick or mosquito is repelled, it cannot bite and transmit disease.

Why Choose K9 Advantix II?

Fleas, ticks and mosquitoes can negatively affect your pet’s health. It’s important to use an effective product that kills pests which can spread disease. Fleas can cause flea allergy dermatitis, an allergic reaction that can lead to constant scratching, severe itching and even hair loss. Ticks can transmit deadly diseases, such as Lyme disease and Rocky Mountain spotted fever. And mosquitoes can potentially carry dangerous diseases, too, including heartworm*.

* K9 Advantix II should not be used in place of a heartworm disease prevention product.

Is K9 Advantix II the Right Choice for Your Dog?

Whether your dog is a winter snow hound or a summer backyard explorer, an sunseeker or an outdoor enthusiast, choose K9 Advantix II to help keep fleas, ticks and mosquitoes from interrupting his favorite activities year-round. If you want to return the love to your dog, take care of him with flea prevention that works to kill the fleas you see and the ones you don’t.

About Bayer

Bayer

Bayer Animal Health recognizes the special bond between pets and pet parents and develops all of its healthcare products with this bond in mind. The essentials of pet health are in the hands of pet parents, including flea and tick control. Bayer is one of the leaders in the development of animal pest control solutions. From ticks, fleas and mosquitos, Bayer products have your pets covered with trusted names like Advantage and Advantix. Certain pests can carry diseases that can be serious health risks to pets. Bayer products are backed by the belief that animals deserve the same care and treatment as humans, making them a treasured Petco partner and supplier.

Bayer Animal Health products are developed for the purpose of keeping dogs and cats flea and tick free. Although you can purchase these products for both the treatment and prevention of these pests from your vet, they are also available over the counter at Petco. The line of Advantage II and Advantage products by Bayer includes monthly topical treatments for both cats and dogs, as well as household cleaning items that help eliminate fleas and ticks in carpets and furniture. Advantage is also available in shampoos, pet sprays, and outdoor sprays that keep pests at bay and pets healthy and happy. Similarly, K9 Advantix II is a regular treatment option for dogs that repels and kills not only fleas and ticks, but also prevents mosquitos, lice, and other pests from biting and infesting your pet.

For pets who prefer the convenience of a collar for flea and tick control, Seresto by Bayer is a non-greasy, odorless collar that prevents fleas and ticks for up to 8 months. Seresto is a great option for pet-parents who prefer a long-term solution rather than a once-per-month treatment. Its sustained release technology ensures that your pet remains pest free for the full 8-months as active ingredients are released in low concentrations for optimal protection.

Shop Petstup for easy access to all Bayer Animal Health products and make your commitment to healthy, happy pets.

4 reviews for K9 Advantix II Flea & Tick Treatment for Extra Large Dogs, over 55 lbs

  1. Rated 5 out of 5

    Best flea preventative I’ve used on my dogs – October 15, 2021

    I have 2 dogs, a doberman and an aussie lab mix, and this stuff is fantastic at keeping fleas off of them so they don’t being them in to my 4 cats. I have a bunch of catnip growing in my backyard to attract stray cats so I can TNR them more easily, but with stray cats comes fleas. The stuff I used before was okayish, but we still ended up having to give multiple flea baths to our dogs and cats every year. Since switching to this stuff, I haven’t found even a single flea all summer. I live in the south, and fleas are intense down here. Even though it’s expensive, I’m absolutely going to keep using this indefinitely.

  2. Rated 5 out of 5

    Has worked great for 8 years! – December 20, 2021

    We have two Rotties and have been using this ever since they had a weird reaction to Nexguard when they were pups. We’ve adjusted the dose along the way, always give them a bath the day we are going to dose and we put it on right before bed and crate them to keep them from licking / accidentally getting the medicine on furniture. It’s usually absorbed in by next evening and they are able to sleep back in their beds w/ us in our room. They don’t like to be two feet from us or one another but are used to being crated when needed.

  3. Rated 5 out of 5

    Works Great! – December 20, 2021

    I am not a big fan of applying this topical medication because there is so much product to apply for an extra large dog. However, we find this product to be very effective for our Golden Retriever. We do a lot of mountain hiking and want all of the protection this offers. The chewable tablets available today sound like they would be easier and less messy but they don’t repel as many insects and I am worried about the side effects of them. So we will stick with K9 Advantix II!

  4. Rated 5 out of 5

    Quick acting – January 17, 2022

    Perfect for our Gerrman Shepherd, Tula, who weighs 73 lbs. It definitely keeps the fleas and ticks away.
