|This topical product that has been around for years is really a potluck type product in my opinion and experience. Many of my clients, who could not afford the other commonly veterinary recommended topical flea/tick pesticides, have found this product a quite helpful much more economic and effective product than the more expensive competitors. . However I have had equal number of clients, who have used this product, been quite disappointed with the results, and their infestations seemed to have gotten worse after starting with this product. I personally don't recommend this product,for my biggest concern that overrides any economic savings that clients have, are the sometimes serious side effects I have seen with certain sensitive pets in my practice and experience. This has ranged from local irritation and greasiness in the coat, to an almost burn like eruption at place of application, to more serious systemic effects like excess drooling, ear itching/irritation and in rare cases neurological side effects including suspected seizures shortly after application. Although these side effects are not common, I feel their severity over rides my ability to recommend this product, I would stick with the more widely veterinary recommended products like Frontline, Advantage or Advantix. I therefore give this product an overall rating of a 2. Its efficacy is a 2 and its ease of use is a 4.
|Within the past year there has been an exciting development in the battle against fleas and ticks.For years, veterinarians have relied on topical medications for control of fleas and ticks, however many formulations are greasy, as well as some sensitive pets may have an allergic reaction to contact some of them. Many clients also worry about the exposure of humans to topical flea and tick pesticides. That is why the exciting new product from Merial known as Nexgard has been such a welcome addition to our flea and tick treatment and prevention options. By using a the ingredient, afoxolaner, Merial has come out with a new product that most fleas and ticks are certainly susceptible. Dogs also LOVE the soft, beef flavored chewable, even without meals. It has also been shown to be safe at up to 5 times the recommended dose.The only down side to this product is that the parasites must bite the dog to be affected, and in some cases this may take up to many hours for this to occur. However, studies as well as clinical experience with this product show that is it very effective in preventing Lyme, Anaplasmosis, Ehrlichiosis and Rocky Mountain spotted fever. This makes it essential as part of any year round parasite prevention program in our dogs. The only rare side effects I have seen are mild digestive upset. I therefore give this product an overall rating of a 4.5, with an ease of use of a 5 out of 5.
