Vet Review

I have started to use this product over the past several months and have mixed feelings about it. A big advantage is the ease of administering the beef and pork flavored tablet but it should be administered on full stomach. And while it avoids the oily liquid pesticides on the back that many clients don ' t like, if a pet is allergic to beef or pork this is a big disadvantage. The best thing about this product (which is similar to Capstar) is the quick kill of adult fleas working within 30 minutes and being almost 100 percent effective against fleas within 4 hours of giving it, and lasting for a month!!! (much longer than a Capstar pill.) A big problem is not only the expense but it also has no tick coverage. In my experience and opinion, I have also seen several dogs vomit when given this pill and it is really not supposed to be used in patients with seizure disorders, which is also a concern of mine in terms of safety. Along the same line, it is not supposed to be used in pregnant or nursing females, as from what I understand when the product was tested there were supposed loss of litter during pregnancy, poor weight gain of puppies and vomiting, the latter symptom which I have seen in clinical practice. In general I am always a little worried about products not approved for young puppies, as the puppies have to be at least 14 weeks of old, according to the label use of this product. It is not a cheap product, and for the above reasons I don't use it often even though it is tremendously effective against fleas. For the reasons stated above, I therefore give this product an overall rating of 2 with effectiveness (for fleas) of 4, the ease of use a 5, and the taste a 4. I still prefer Front line, Advantage and K9 Advantix despite the oily spot because of the increased coverage of parasites, and my concerns about safety

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.
