Vet Review | While this product offers an economic alternative for killing/repelling fleas and ticks for 5 months, as well as preventing the development of flea eggs into larvae and adults, I have personally not found this product effective in my experience and opinion. The clients I have spoken to who have been pleased with this product have found it more effective as a flea preventative, rather than once an infestation already exists, where other products such as topical front line or advantage would be preferred. I have also seen that in some dogs local skin irritation and hives can occasionally occur in sensitive pets, which usually resolve once the collar is removed. I also have concern for cancer and neurological effects with exposure to any prolonged pesticides. While it is a nice benefit that the collar works even when wet, because of my concerns about overall efficacy and safety, I do not recommend use of this product. I give it an overall rating of a 2 with an efficacy a 2 and ease of use a 5. | 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 | 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. |
