It makes me feel better to know there are a lot out there that have had success with the Revolution. It is my understanding that if they use the Revolution they are not suppose to use the interceptor for the heartworms also. When my vet switched Zoe' he had me wait until the application of Revolution had been on for the full month, then we started the frontline and interceptor. I think we will give this a try on the new baby, he tests annually for heartworms as a precaution. She had her second dose on Saturday with her 12 week booster shots (it was a free dose), I think he forgot that he had already done her free dose the last visit. Oh well, we just got an added bonus. Thanks for all the responses.
