|Advantage kills fleas, Revolution kills fleas & keeps the eggs from hatching, also treats/kills ear mites, heartworm, roundworm, and other worm-parasites. That's why it is usually more expensive.
fyi, Frontline's difference is it also kills fleas/ticks, but not mites or worms.
The thing to think about is how much exposure you have to parasites by going outside or living with a dog who does.
Hope this helps, if you have more questions, just post again.
