Customer Reviews

Rated 4.6 out of 5 by 51 reviewers.
Rated 4 out of 5 by Working well Switched to Advantage II from Frontline Plus that I had been using for years. I personally think that the fleas have built up a resistance to the active ingredients in Frontline Plus because it used to work well, but recently seemed to have little affect. Of course no one topical is going to take care of an infestation. You will still see fleas on your pet unless you do a total regiment of treating the yard, bedding and carpeting. At a minimum bedding must be washed and floors vacuumed regularly. If you bath and treat your pet, and then they go lay down on bedding infested with fleas...well you can bet you will see fleas on your pet. I used Advantage II on my 5 dogs ranging in weight from 6 to 22 lbs with no adverse reactions, which is just as important to me as how well the product works. I have to buy two different doses due to the weight range of my dogs. Be sure to use the right dosage for the dogs weight of course. So far working well, have seen a drastic reduction in active fleas on my dogs. Of course when using any kind of flea prevention (aka: pesticide) research risks, as well as benefits. July 14, 2016
