I forgot that you asked me about Revolution in that other thread...

The vet I worked for throughout highschool carries revolution at his clinic. He has told me before that he has had dogs on it come in that had heartworms, and that he has heard reports of it not being as effective against heartworms. Nothing is 100% effective, but revolution is supposedly less effective than the others on the market.

I did a little searching online and found this as well:
A review written by a veteranarian Revolution for Dogs review
Revolution was introduced back in the late 1990’s as the new heartworm, flea and tick all in one product for dogs. My office has been dispensing the product for 6+ years and I have a pretty good grasp of its abilities. First, if you live in a high heartworm endemic area like my office in St. Thomas USVI, then this product is not for you. We have found the product to be less then 100% succesful in heartworm protection as compared to Hearguard or Interceptor. Having said that, Pfizer will pay for any dog’s heartworm treatment that can prove Revolution purchases from a veterinarian (not online pharmacies). However, you still do not want to risk your dog’s life even if it is free. In lower heartworm areas (the Northeast USA…) this is a good heartworm prevention product. Second, the product is poor on ticks. Plain and simple, not my first choice. I prefer Frontline and a Preventic collar. This product’s best feature is its flea control. Revolution is a revolution in the world of flea control….the best.
Hope this helps!!

A review someone wrote whose dog got heartworms after being on Revolution for 3 years Revolution does not work! - Pfizer Revolution (Selamectin) - Epinions.com
Our vet put our (3) three dogs on it three years ago since they were puppies. We purchased revolution from our vet and applied as per his instructions. One of the dogs tested positive for heart worm even though it was on revolution for (3) three years. Our vet informed us that he thought Pfizer would assist in paying for treatment to remove the heart worms, they didn't.

Another review of a dog getting heartworms I do not trust Revolution! - Pfizer Revolution (Selamectin) - Epinions.com
We adopted our Jack Russell 1 1/2 years ago. He was given a complete clean bill of health by a vet the day we took him home(including a heartworm test.) You can imagine my surprise at his next check up a year later, when he tested positive for heartworms. He had been treated by Revolution monthly from the time he came to live with us. W are crushed! I have been talking to many people about this. There have been quite a few others with the same result. Now I have to put my dog through a difficult and expensive treatment. I am very disappointed!
