Rated 4 out of 5by LMerchant 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 1 out of 5by Mary5903 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
