Revolution is awesome. It begins to work in 30 minuters our vet told us. We put it on our puppies, and in 20 minutes flea were fleeing and staggering and running in terror. It was interesting. By the next days sickly, dying ticks came off. It also prevents heartworms, and lot of other worms I think, and mange too I believe. Its amazing stuff
