My 5yr old Golden Retriever and I will be moving from Ohio to South Florida this May. My Vet said that I will need to continue to use Sentinel AND use Advantage, or another additional Flea medicine to prevent fleas. Is this really necessary - and more importantly - could this hurt my dog's coat, or be toxic to him? (I understand that Sentinel is for parasites as well as fleas.) Thank You.
It depends on how bad the flea infestation is in your area. Sentinal is used to prevent heartworm disease and fleas. vetcare
