my two are on Sentinel, their is a problem with mosquitoes in my area now that we have moved, so they were both tested and the results were negative for parasites and heartworm. They each take a pill once a month and so far their have been no problems. I can only get the medication from our vet and a 12 month packwas $134.00 , so every 6 months I need to go back for anther RX. it goes by weight also, and I saw they were going to give them the 11 pounds one and up, I told them my dogs are not 11 pounds , so they gave me the 10 pounds and under, which made me feel 100% better
