Reliable Protection—No Fleas, No Ticks, No Worries
K9 Advantix II has been our go-to for years when it comes to protecting our dogs—especially with all the outdoor time they get on the farm. It works fast and effectively against fleas, ticks, and mosquitoes, and we’ve had zero issues since using it consistently.The application is simple: just part the fur and apply it along the back. It dries quickly and doesn’t leave a greasy mess. What I really appreciate is that it repels pests before they even bite, which gives me peace of mind—especially in the warmer months when ticks are everywhere.Our dogs haven’t had any adverse reactions, and they’re outside constantly—running through tall grass, woods, and around livestock. It’s held up through baths and light rain too, which is a big plus.If you live rurally or have active outdoor dogs, this is one of the best defenses out there. Worth every penny for the protection it provides.

Works like a charm.
Worked pretty quick. After 12 hours my corgi/blue heeler was able to calm down from the scratching. She still had some fleas as I checked. After 24 hours, she was so relaxed after days of non stop scratching.It’s been 3 days and haven’t found a single flea.

good product, but so many years after r and d were done, how does it stay so pricey?

Our dog had a severe allergic reaction.
Our dog had a severe allergic reaction to this. About 2-3hrs. after we applied it he started scratching, breathing heavily and running around. I bathed him twice and administered Benadryl. He's doing much better now. We'll monitor him the next few days and find an alternative flea and tick treatment. I can't give this product a bad review because I understand it can effect dogs differently.Update 48hrs after application: Because we bathed our dog as soon as he showed signs of a reaction and administered Benadryl, we lessened the severity of his symptoms. He's not twitching or biting at his tail. His breathing is normal and he's sleeping soundly.

Works great!
This works very well and kept my 16yr old pittie mix flea and tick free with no side effects. We live in a highly populated "deer area" with tons of woods around us too! No complaints here! Definitely will purchase again!

Worked for a while and then all of a sudden it doesn't work so good switching brands
My dog still got many ticks well on this I don't think I would recommend it I'm not sure why it didn't work for my dog ... He's been on it for got to be over a year and last spring he didn't get any ticks he didn't get any last summer either this year numerous times like as in more than 20 in less than a few weeks Big difference when it goes from zero to no longer protecting him. But I gave it the length of the last dose to see if there's a better one out there currently He's on the last few days of this one
