Rated 4.7 out of 5 by 223 reviewers.
Rated 3 out of 5 by My dog seems to be allergic I have always used Frontline Plus on my dog, but this time I tried Advantix II. It was cheaper for the dosage, so I thought I would try it. I applied it according to instructions, but since doing so, my dog has been scratching near the spot where I put the medicine. I wish that I had bought my old flea meds. May 15, 2016
Rated 5 out of 5 by Works almost instantly! So happy with my purchase! The best price I have ever found. Product worked almost instantly! VERY HAPPY WITH CHEWY! May 18, 2016
Rated 5 out of 5 by This product is excellent!! I have been using K9 Advantix II since my dog was a puppy...I have never seen one flea or one tick and as far as I know he has not had any issues with mosquitoes either. Also there has been no problems with any reactions from the medicine to my pet. I highly recommend this product. May 17, 2016
Rated 5 out of 5 by This product works very well I have been using this product for three years on two different dogs. In all that time I have not found any of those pests on either of them. I live in a rural area so there are plenty of opportunities for ticks or fleas to hop a ride. But this stops them. I am very satisfied and will purchase it again without hesitation. May 7, 2016
Rated 5 out of 5 by Best Flea and Tick medicine K9 Advantix ll is my go to product.. I've tried others but they don't work like K9 Advantix ll... We never had an issue with fleas however, ticks and mosquitos are a big issue in my area... I treat my girl year round and I hardly see any mosquitos flying around her and I have yet to find a tick on her.... I do think they should make a Kid Advantix ll ;), I find more ticks and mosquitos bites on my kids..it's awful May 9, 2016
Rated 5 out of 5 by Easy to use Love this product as it is easy to apply and you can't beat chewys price or shipping May 17, 2016
Rated 4 out of 5 by Good deal & quick delivery Good deal & quick delivery. The only reason this isn't a 5 star is the box was damaged, but luckily the damage didn't affect the product. May 16, 2016
Rated 5 out of 5 by Solves my insect problem I purchased Advantix II because I will be moving to a climate where there will be more mosquitoes than where I presently preside. Since I had already been taking care of ticks and fleas with the product I was using and I needed to address mosquitoes I made this purchase. May 11, 2016
