“I have used Sentinel for heartworm protection now for all my dogs for the last 10 years at least. It also has a flea egg prevention which breaks any picked up fleas from making any eggs. I am an avid dog show goer and contestant exposing my dogs to the flea problem, without having the flea problem at home. so I seem to get enough coverage, but I do check regularly for ticks during the summer and fall months. I try to avoid using too much poisons on my dogs.”
“This is a great defense medication to keep my dogs from getting heartworms & helps with fleas. They have been on this for a long time. & it's the most reasonable in price than any other brand.”
