I personally don't like to medicate unless needed so personally I do not use revolution. But if you live in a location where ticks & mange are extremely popular I would suggest using that.

Otherwise my favorite & what I use is interceptor & Advantage.

I would stay away from the 6 month heartworm vaccine, a LOT of dog have bad reactions, even deaths. (proheart is the name)

And Advantix should NOT be used on or near any animal EXCEPT dogs, so if you have cats in your household I would not use it.
