Product Detail: K9 Advantix II

K9 Advantix II Product Overview

K9 Advantix II is an easy to apply, once a month treatment for dogs to repel and kill fleas, mosquitoes and nasty ticks, whilst also killing lice and repelling biting flies. It is waterproof and thus dogs can still be bathed and swim on occasion.

K9 Advantix II will start killing fleas already infesting the dog within 12 hours of application, and those re-infesting the dog within 2 hours.

By repelling and killing fleas, ticks and mosquitoes, K9 Advantix II may save dogs from contracting blood-borne diseases readily spread by these parasites. They will also be saved from the discomfort of constant irritation and itching caused by these parasites as well as lice and biting flies.

Treatment with K9 Advantix II can begin from 7 weeks of age.

Tips and Tricks for Using K9 Advantix II

Most animals will tolerate the application of a spot-on topical treatment such as K9 Advantix II quite well. However it might prove helpful to have assistance from another person if your pet refuses to co-operate. Another suggestion would be to offer the dog a treat whilst applying the product. For dogs which tend to roll around after application of the product, taking the dog for a walk immediately after application can avoid this problem.

Active Ingredients of K9 Advantix II

K9 Advantix II contains a mix of imidacloprid, permethrin and pyriproxifen.

Cat in home...Don't use!
Oct 15, 2014

We by mistake purchased this vs. advantage. We had no idea that this was HIGHLY toxic to cats and our dogs and cats are very cuddly with one another. One of our cats had a HORRIBLE reaction due to contact with this product on the dog. Tremors, loss of coordination and a hefty vet bill for overnight stay at ERvet was the end result. We made a mistake of having this product in our home. We will not do that again. It is not enough to have a DO NOT USE ON CAT on this product....this product nearly cost our cat his life. Please be cautious if you share a home with dogs and cats.

Our adopted Retriever-Hound mix Red hasn't had a flea since his first application of this product. When we first adopted this pup, he was covered with unwanted friends, but no more, none on the dog, none in the house, and we live in the South where before using flea protection products, we had to treat, dog, house and yard, and never won. Thanks for selling this great product at good prices and for your fast shipping. I recommend Pet Shed to all my dog loving friends.

This is a great product!

My little dogs are allergic to flea bites. I have used all the other named products and they were still miserable. I tried this flea product and nothing gets on them to bite them. I love this product and I am sure they do too!

Price and Protection
Jul 21, 2011

Bottom line, the price at PetShed can't be beat and the protection my dog needs depends on K9 Advantix II. Scout (my German Shepard) was using a different popular product, but was itching horribly. I called a vet and she told me that they've seen fleas starting to resist certain products, and to switch to K9 Advantix. I immediately went to Petshed and ordered it (even though her itching turned out to be allergies). Still, I'm glad I switched knowing what I know now!

Healthy and Safe

We love K9 Advantix II!! Our dog Amelia was living on our street when we took her in. Her coat was dull, flea-infested and her ribs were showing. So sad. Now, she's a shiny, happy puppy dog - nearly 75 pounds. Finding a good product that could cover all her health needs - flea AND tick - really made a difference. We take her hiking and swimming and she loves the dog park. We can do all this without worrying about ticks or fleas or transferring any of these to our other animals in the house. A healthy animal is a happy animal and that makes us happy, too.
