I've read a little about revolution, but I haven't tried it yet mostly because my vet hasn't started carrying it and I'm in a rural area. I have been using frontline for fleas and ticks plus interceptor for heartworm, and it does the job. The all in one of revolution is appealing though.

I normally only use the frontline from mid spring through late fall because we don't have flea issues once it gets cold, but I treat with interceptor year round. There aren't mosquitos in the winter but interceptor prevents other worms too, and I take in a lot of fostors so I figure better safe than sorry. I have a foster now with awful roundworms that we are treating. The first day I got him he went to the bathroom and nothing but worms came out. I have never seen a case so bad in a grown dog. yuck!
