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

I recently completed a small clinical trial using the Flea 3X topical product for cats. And I must say that the initial reports on the safety and efficacy of this product has been excellent. With the main ingredient being the tried and tested fipronil, this product is very effective in controlling fleas, ticks and chewing lice. Clients have loved the economic savings of this generic alternative product to Frontline. It is also manufactured exclusively in the United States, as well as carrying the trustworthy and reliable 1-800-PetMeds brand on the packaging and label. Thus far, clients have reported back that fleas and ticks are killed very rapidly, and that protection lasts for up to several weeks. I therefore can highly recommend this product to all of the feline guardians as a wonderful and economic alternative to more expensive topical products on the market.

An exciting and brand new product now available combines the main ingredient of Interceptor milbemycin with a powerful flea insecticide known as spinosad. Given as a once monthly heartworm preventative, this product also will control and prevent whipworms, hookworms and roundworms, in addition to preventing heartworms. The additional ingredient spinosad allows effective flea and these internal parasite control all in one pill, making it quite convenient for clients. As with any pesticide rare digestive tract and neurological side effects may occur but this has not been a major problem in clinical trials. Since it is relatively new I will have to see how this product performs on the fleas but it seems to have excellent potential. I give this product an overall rating of a 5 with an ease of administration a 5 as well, taste a 5.
