Vet Review | This is a wonderful quick kill short duration flea adulticide that begins killing adult fleas within 30 minutes. It does not leave pesticide residue on the pet or in the home, and when combined with its sister product Program, offers an excellent non-pesticidal alternative for all around flea control to topical pesticides that some clients are concerned about. I have rarely seen any side effects in my clinical experience in using this product. I have used it up to once daily in flea infested animals, but more commonly I use it once or twice weekly during flea transmission season along with the once monthly Program product. Another wonderful advantage of this product is its safety in administering it to pregnant or nursing dogs, who can often be a big source of fleas to their nursing puppies or kittens. The biggest disadvantage to this product is that it only kills adult fleas, but this problem is easily circumvented by combining it with the Program product. | 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. | Sentinel is a wonderful combination of the heartworm prevention pill interceptor and the flea control product program both in this one pill. Many clients enjoy the convenience of having such broad acting internal and external parasites in one pill, without having to worry about giving two separate medicines. Lufenuron, which is the main flea control ingredient, stops the flea life cycle in its track at the egg and larval stage, thus being like a birth control pill for fleas who get on our pets. Given that the main problem of fleas is how rapidly they reproduce, this pill literally stops escalating growth of flea populations, before they can become established in our homes, where most of the flea life cycle occurs. The main disadvantage to this product is that it does not kill or repel adult fleas, so in situations with already established heavy infestations, it is best combined with a great topical product like advantage or front line or with the oral adulticide flea pill Capstar for maximal effect. The only other rare disadvantage I see is the slight increase in reactions when two products are combined into one like this, but fortunately this is not common in clinical practice. With milbemycin for prevention of heartworms and controlling and treating most common intestinal worms, I overall highly recommend this versatile product. |
