I have used it since last spring. We have no problems with fleas around here, Thank God... so not sure how wll it does for them. I like it as ony one treatment for several parasites and it is only about $12 a dose per dog vs heartguard, frontline $$$.
I have used Revolution with my cats for as long as I have had them and I really like the product. One of my cats did have a slight hair loss reaction to it, so I now make sure to not place the Revolution in the same spot as the previous months dose.
When I got my pup I automatically thought I would use it for her too since I liked the idea of a one product treatment. However, my vet pointed out that the Revolution for Cats actually is designed to treat/prevent more than the Revolution for dogs. I cannot for the life of me remember which things, but my vet recommends Frontline and Heartguard for the dogs and Revolution for cats.
The reason I didn't want both heartguard and frontline is the cost. It would be double that of Revolution. I have an appt with the vet on the 27th. Don't like them but they are cheap. I don't go to the other vet till next year if I don't see her at the dog club. Plus the cost difference. I took KC in for her second shot and it was 45 euros for the distemper/rabies. That is 80 USD! just for the one shot! Germans are crazy expensive. But the vet is so worth it, I just wish we could afford to take all the pups there for everything.
