Rated 4.1 out of 5 by 780 reviewers.
Rated 5 out of 5 by Effective We have been this using this product several years and never disappointed. August 19, 2015
Rated 5 out of 5 by Love this product! I have three rescue chihuahuas so keeping them healthy and happy is priority. I find that K9 Advantix II works just as it promises. We have no fleas, ticks or mosquitos in our home even though all our fur babies get to play outside several times a day. Buying in packs of 12 really saves money, too. Not one of my "kids" has ever gotten sick or had a bad reaction to K9 Advantix II. I would imagine if you bought the wrong size, it might not agree with them. Stay within the weight boundaries and you will do fine. August 17, 2015
