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 Flea 4X topical product for dogs in my veterinary clinic. And I must say that the initial reports on efficacy and safety has been excellent. With the main ingredient being the tried and tested fipronil, this product is very effective in controlling fleas, ticks, chewing lice and mosquitoes. It is also labelled to control mites that cause sarcoptic mange in dogs as well. This product is a wonderful generic alternative to the Frontline product that has been out for years. Clients have loved the economic savings of this product over similar topical flea and tick preventatives. It is manufactured exclusively in the United States, as well as having the trustworthy and reliable 1800petmeds label on the packaging. It is also water proof for those canine patients who spend a lot of time outside and/or swimming during the summer months. Clients are reporting back to me quick flea and tick killing that lasts up to several weeks in treated pets. I highly recommend this product to those canine guardians seeking out an effective and economic alternative to similar products on the market.

For my clients who prefer an effective non-pesticide manner of preventing and controlling fleas on their dogs and cats, program offers a wonderful alternative. When this product first came out, I used to educate my clients on the fact that it was in essence a birth control pill for fleas. The main ingredient lufeneron is an insect growth regulator that does not kill adult fleas, but sterilizes adult fleas and prevents them from laying eggs that develop into larvae and future adults. Each adult flea can lay up to 2000 eggs in its life. It is because of this effect on flea development which makes program such a wonderful preventative. For existing flea infestations, I don't find this product works as well unless it is combined with oral Capstar, which kills adult fleas on cats and/or topical products like Frontline or Advantage. I have found this product both very safe and effective with only rare side effects seen i.e rare digestive upset. It is best given with a meal for maximal absorption which is hard on some kitty owners My overall rating of this product is a 4 with ease of use a 4, taste a 4 and efficacy a 5, in particular for preventing flea infestations before they become established.
