Vet Review

I love the broad acting antiparasitic effects of this product, which covers protection against a wider variety of pests to our pets than the competition. I feel it works the quickest in terms of flea/tick killing, and I love the fact that it repels fleas and ticks as well. Given that we are uncovering new and emerging tick born diseases, I prefer a product that repels in addition to quickly killing ticks, as well, and thus prevents tick attachment and transmission of disease. We are also now recognizing that mosquitoes can transmit diseases like West Nile virus to dogs, and so the added protective benefit of Advantix on mosquitoes and flies makes it quite attractive, especially for those clients whose pets spend a lot of time outside in the yard in the warmer months, when flies are most active. With this product I see much less fly strike and maggot infestation of outside dogs because of this added benefit. By repelling mosquitoes, we also get less transmission of potential heartworms to dogs. I have found that some smaller breeds of dogs are sometimes sensitive to the permethrin ingredient in this product, occasionally becoming excessively sensitive after application. I also find that although the product is labelled as water proof, on those pets, who are frequently bathed or swimming for long periods, that the product may need to be applied more frequently than once monthly. Some clients also find it somewhat more inconvenient in larger breeds having to apply the product in several spots, rather than in a single spot like its competitor.

For clients that prefer an outstanding topical medication that has thus far had an excellent record of efficacy against both fleas and ticks. This product includes 3 very powerful and synergistic flea/tick pesticides that work in slightly different ways, with one preventing development of flea eggs and larvae, while another ingredient quickly kills; killing probably the fastest of any products on the market, starting to act within 5 minutes. Ticks will take somewhat longer, but within 2 days most ticks are killed. The addition of the permethrin ingredient does add the benefit of this product in BOTH repelling and killing ticks, , as well as the additional benefit of killing and repelling mosquitoes, the main vectors of heartworm disease in dogs and cats. As with other topicals, occasionally pets will develop an irritation or sensitivity at the sight of application, with some pets being occasionally restless, agitated, or fidgety. On rare occasions vomiting and/or diarrhea may be seen but this has not been much of a problem in clinical practice, where most pets seem to tolerate the product quite well. While the trio of main ingredients in this product seem to provide additional efficacy and coverage of various stages of the external parasites, including the benefit of repelling them, I am always a bit cautious about combination products like this, which rarely may lead to unknown chronic side effects that we are not yet aware of. With that consideration, this product is still an excellent and effective choice. I give this product an overall rating of 4 out of 5.
