K9 Advantix II XL Dog Flea, Tick & Mosquito Treatment
March 31, 2024
So far, so good! My German Shepherd and Rhodesian Hound both continue to scratch a bit. However, we've only just put the treatment on them two weeks ago. I give five stars without experiencing the time and impact fully yet. We are very happy with shipping, packaging, timeliness, good customer service. Thank you!!

Best topical flea meds
March 16, 2024
Advantix is the only product I use on my dogs. The other 2 name brand topicals are completely inferior. I only wish they made something for cats this good.
  • Works better and longer than stated.
  • Offers protection for more than just fleas
  • It's a pesticide. In a perfect world I wouldn't have to use it or anything else at all

My 8 year old Cavachon has been on this product all her life. Recommended by her vet due to her sensitive skin. Product has worked very well, and with no side effects.
  • Works well.
  • Expensive, but EntirelyPets offers a lower price.

Always Works As Described
July 23, 2022
I'd give it full marks for efficacy, in other words, a full five stars. However, the price has escalated considerably over the years, far faster than most person's paychecks have done. If the product was available at a more reasonable price it would be so much more attractive. I've used it for years on multiple generations of my dogs and always been pleased by how well this product protects.
  • Simply put: it works
  • Simpy put: exorbitant price which has escalated much faster than overall inflation

August 26, 2021
K9 Advantix works very well for keeping fleas away and killing ticks that get on my dog. That's important to me, since I live in the country and we have armies of ticks in the spring and early summer. It's easy to put on which is good, since I have a wiggly dog to use it on. It's a little pricey, but worth it to keep the pests off.
  • Works on fleas
  • Works on ticks

Works on large dogs too
August 8, 2021
About 20 minutes after application my dogs are absolutely flea & tick free. My dogs have plenty of woods and grass to venture in and they are free of pests.
  • Works fast and for 30 days.
  • Afraid to get them wet.

I live in Canada. Flea medication is so expensive here. I was glad this came across the border without any problems.
Works Great but Follow Directions
January 22, 2021
This works great when applied exactly as directed. Please read directions carefully and ask your vet if you have any questions so you will be sure to apply this product correctly. Note that this medication can be rendered ineffective if you give your pet a bath too close to applying this medication. I still prefer this medication over giving my pet a pill to take because she has a sensitive stomach.
  • Works if used as directed
  • Expensive

We live in the “sticks” with a lot of deer ticks & in hotter weather, fleas. This protects our Choc Lab and us from being bothered by these pests. Thanks

Great flea/tick/mosquito preventative for dogs
April 4, 2020
This product is great. It works well to kill the fleas and ticks on the dog as well as prevent any additional ones. Not all flea and tick preventative topicals work on mosquitos but this one does.
  • Cheapest on EntirelyPets' website if purchased in larger quantities and the 15% discount is applied
  • Not very affordable for all people

Good quality product that I've used for years
December 31, 2018
I started using K9 Advantix II about 5 years ago, and have been very satisfied with it. I was previously using Frontline for over 10 years, but switched to K9 Advantix II when my vet told me that it prevents and treats more things than Frontline does. It is also a little less expensive too! I've attached a comparison chart of the two products.

October 29, 2018
The fact that K9 Advantix II works not only to kill fleas and ticks, but has a repellant feature as well sole me on the product. As well as the Bayer name. So far, so good, and I've used it with success for over a year.
  • Repels and kills pests.
  • A bit greasy for a few days.

Did not work enough
