Rated 4 out of 5 by Easy Treatment We've been using Sentinel for our dog, Boone, for the aspt four years and it works well. Boone eats it without a problem. All annual heartworm tests have been negative so the product works. 07/02/2016
Rated 5 out of 5 by Awesome Customer Service Great for your Pet and I thank Petcarerx for the great customer service every time I do an order! 07/01/2016
Rated 5 out of 5 by Very effective, no side effects. we've used this product for many years, very satified. GREAT price. 07/01/2016
Rated 4 out of 5 by Fast shipping, good price for a heartworm preventative We have been using Sentinel for a few years now and PetRx saved us quite a bit this year. This keeps our dogs healthy and heartworm free and is incredibly convenient to order online with renewal with the PetPlus program. My dogs eat this like a treat - no bread or peanut butter or anything like that needed. They have been flea-free their whole lives so I don't know if that is our yard being well kept or if it is due to the Sentinel. Same for heartworm - this monthly treatment appears to have kept them healthy. They have no side effects whatsoever when taking this product. This product - even though some think it takes care of Ticks, it does not. If you want tick prevention, you have to get another product. Our veterinarian also explained that it does not kill adult fleas, it only kills flea eggs and prevents them growing on the dog in the fur, so if you have outdoor pets or they run in unmowed fields, etc, you might want something that keeps the adult fleas off of them as well. But for us, this is all we need. PetRx delivered this to us fast and with no hassles. Thanks! 06/23/2016
Rated 5 out of 5 by Using Sentinel for years with excellent results. We are very happy with this product. Been using Sentinel for many years for our dog. 06/10/2016
Rated 1 out of 5 by Not effective for my pets I don't think this product had enough ingredients to keep fleas from attacking my two dogs. We fed them the products per the directions. We've since requested and are still waiting to receive a dose of Capstar to see if that can improve their condition. 05/26/2016
Rated 5 out of 5 by Worry free for another year When we bought our home we discovered that a previous owner had lost a dog due to Heartworm. We sure do not want to repeat that have to be diligent about a preventative. Sentinel is perfect for that and PetCare had by far the best price! 05/26/2016
Rated 5 out of 5 by Great product Great product as it combines flea and heartworm into one pill. However, my dog does not like these and I have to give it to her with some peanut butter. This has not been an issue with other pills. 05/02/2016
