I have had success with both. The advantix is a smaller dose than the frontline. I like that factor. I am now using Revolution for both dogs. My vet stands firm on it working for the heartworms. Believe me I have asked him many times if it is as good as a seperate med for heartworms. He says that it is. I have seen an advertisement in the past few days that indicates advantage is coming out with a new one that does the same as the Revolution. Has anyone seen this?
