k9-advantix 11 works perfectly for my country dogs, one of which has a life threatening reaction to even one tick. I have never had another episode on this poor guy by being diligent in regular use of this product on all five.

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.
ProsCheapest on EntirelyPets' website if purchased in larger quantities and the 15% discount is applied
ConsNot 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.

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.
ProsRepels and kills pests.
ConsA bit greasy for a few days.

Have tried many different kinds of flea treatments over the last 30 plus years and K9 Advantix II has been the best to insure my home is flea free. With so many dogs I can not afford to have any chance of fleas breading and this is the best which is also recommended by my vet to add to the to the quality of the product.
