Good quality product that I've used for years
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.

Works well for my Golden Retriever
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.

Did not work enough
I wanted To try a new preventative since my current one was not working. This helped very little for my dog's fleas. I had to replace it after a couple of months with another product.

Pet lover
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.

K9 Advantix
the product is fine but because the customs paper work was not done I had to pay an additional $22.00 which was really disappointing. I will not order again. Between the shipping cost and the custom cost it makes the product more expensive than buying it at the vet.

Won't use anything else
We have always had great success with using Advantix. I love that it also repels mosquitoes. We just returned from a weekend of camping deep in the woods with our dog with no problems keeping the bugs away. He is a happy pup!

We Love it!
We love this product. We have used it before, and it really works. I highly recommend this product! We have tried different brands of tick treatments in the past, and those products did not work! Our black lab got ticks from those other brands. With this product, he no longer has or had any ticks.
