 Well a trip to the vet and $85 later we got some Revolution 20-40.  The vet says it works wonders.  If a bird land on the dog it dies instantly.  Just kidding.

 You should have your dog checked for existing heartworm before applying Revolution . . . . it might harm your dog if it has an existing heartworm problem even if this is also a heartworm medication. It probably says that right on the box.
I believe Revolution works as per my first example above, eventually going into the doggy blood stream and solving your problem through time and acting as a preventative in the future.
HOWEVER, it probably doesn't solve things for you immediately, the current flea infestation. Fleas are present, eggs have already been laid. You should probably consider a Flea Bath shampoo for the dog to neutralize what's already on the dog and a spray to apply to every orifice of the house, doggy blankets, etc, if the dog has been inside. I think you can get those things at a department store like Wal-Mart or something.
We used Revolution but now we use Advantage Multi-100.
