I really wanted to put Maddie on this because I feel like she drowns when I put all the frontline on her but I have read reviews where dogs are still getting heartworms and you should supplement with another heartworm preventative. My vet recommended frontline plus, so she could be protected from ticks too, and sentinel. She said she has come across dogs that get heartworm with Revolution. She said it probably is due to misapplication, but still, I don't want to take my chances. Good luck! |
