Revolution is good
It worked for my yorkie really well. I have never saw a tick or flea on him since we started it. There are many natural ways to deter fleas though. That being said though, do a google search for Natural flea and tick prevention. See what you come up with
I don't like the idea of putting chemicals on dogs that are not safe for humans to touch, and the fact that the boxes say that if it comes in contact with our skin, to immediately wash it off...That can't possibly be good for them. But Revolution is supposed to be one of the "safer" ones...It's for heartworm, ticks, fleas, etc.
