Rated 4.7 out of 5 by 304 reviewers.
Rated 5 out of 5 by So easy! The price was so good for this six month supply. It was my first time applying a flea and tick treatment and it could not have been easier. We'll see if it is as effective as claimed but I feel secure because other customer reviews gave it high marks. October 23, 2016
Rated 3 out of 5 by Not sure about this I have used K9 Advantix for a couple years now and it's worked great. My dog has went all summer without a single scratch up until September. Since then I have found a flea on her a couple times and she has went into full blown flea allergy dermatitis and has been on allergy/steroid med for weeks now. I have never missed a dose of Advantix on her and don't understand why this is happening. I loved this product but it doesn't seem to work anymore. October 19, 2016
Rated 5 out of 5 by Exactly as it states, Shipped in US, Shipped fast and free :) It's wonderful to get the exact product from the US (although many are made overseas). I've had a couple of other dealers and I'd get a shipment from Hong Kong or New Zealand and it didn't work as well as what I had bought from my vet. This one does at half the price. My vet charges about $30 a month for one of these, I got 6 months work for considerably less and it's working great on our Cairn terrier mix. No ticks and no itches for her or us. I will be back and highly recommend you check here first. October 17, 2016
Rated 5 out of 5 by Have used this product for many years We have a very strong flea population here and after having problems with Frontline I've been told by our friend and Vet to use this product. Since changing I've never had a flea issue and this has been over 10 years now. I would not go back to any other product. Ticks die off fast as well as it repels mosquitoes. October 22, 2016
Rated 5 out of 5 by No flea or ticks with this medication I am not one to bad mouth a product, that being said, at one time I used Frontline for my dog, think the ticks became immune to frontline so I changed due to the recommendation of fellow dog owners and now use Advantix without and issues its a great product IMHO. I hope you have the same results. October 21, 2016
Rated 5 out of 5 by First time user, great Job so far! Per Recommendations from our vet I switched from frontline to advantix and We Are 2 wks out so far so good. October 22, 2016
Rated 2 out of 5 by Does it work? I've used K9 Advantix II in past and it seemed to work OK, saw reduction in scratching within a few days. This time, dog is still scratching, although not as much as before treatment. Still, I expected more effective action, based on customer reviews. Don't know if fleas are becoming resistant. Will have to see how second month's treatment goes. However, am very satisfied with this vendor as price was good and delivery quick. October 9, 2016
Rated 5 out of 5 by Fantastic product Just started using this product earlier this year. Very effective in all the states we have traveled in with our Rv , 2 boxers & 1 English bully. We live in tx & mosquito issue is extreme. Dogs tolerate it well w no adverse side effects noted. Best price found at chewy website October 19, 2016
