Customer Reviews

Rated 4.6 out of 5 by 88 reviewers.
Rated 4 out of 5 by good product this is a good product for my needs. I have a T cup Yorkie about 4 pounds and vet recommend it to me. I had set this up on order replishment but I buy the 6 pack of it found it to be a better value. But the auto ship plan ships every 4 months so I end up cancelling it. But I will be ordering again in 6 months. They make products that you can feed to your dog but many Yorkies tend to be picky eaters and mine would not touch those treatments. I will not force feed my pet because she is so small she could be injured very ease. July 23, 2016
Rated 4 out of 5 by Quick friendly service So far, so good, advantix II seems to work as advertised, my dog rarely scratch's and I haven't seen or felt flees in my apartment. July 23, 2016
Rated 5 out of 5 by Top notch product Well known and well respected product at a great price. July 15, 2016
Rated 5 out of 5 by Great quality product! I have used AdvantixII for my dog as long as I have had her. The consistent quality of this flea and tick control medicine is why I continue to use it. Chewy.com had the lowest price on AdvantixII that I could find. They are cheaper than most companies online, and if there is a problem with your purchase Chewy.com is very easy to work with on your return/refund. I highly recommend AdvantixII And Chewy.com!

Rated 5 out of 5 by Product offers a lot of protection I have used this product on my small dog since she was old enough to use Flea & Tick Treatment. We have several open acres and she runs around with our large dog. We also have deer and other wild animals that come onto the property. With that in mind, it is very important that the dogs be protected. This product does that and more. June 24, 2016
Rated 5 out of 5 by This product is very effective. This product works for my little 4 pound Chillion dog without any bad side effects as some other brands caused. June 29, 2016
Rated 5 out of 5 by Great Option at a Great Price When needing to stock up on monthly flea drops, I researched the comparisons between major brands. While Frontline was a more "natural" alternative, K9 Advantix II offered better protection with regards to what it kills and repels. Chewy, of course, had one of the most competitive prices available! She's on her second dose, has had no reactions and is flea, tick and lice free. June 22, 2016
Rated 5 out of 5 by Good product - great price I shopped for best pricing on K9 Advantix II Flea & Tick Treatment for Dogs. I have 2 dogs and have used this same product for years and like how it works. This year the fleas and ticks are really, really bad in this area - no real winter, more like swinter. Chewy offered the best prices, plus a discount is offered if you sign up for auto-order. It's a deal!! June 17, 2016
