Could point me in a direction for finding a vet that doesn't make you give shots? Also, would Heartworm be considered one of those types of medications that dogs don't really need?

I absolutely love your site, and I've bought several items. I want to find a vet that won't make my dogs get shots, any recommendations on how to find a vet like that? Also, is it ok to give "Revolution" for fleas, ticks and heartworms? or do they not need heartworm med's? I wasn't sure if this is also unnecessary or not like vaccine boosters. I had a schnauzer, died at age 9, had every problem under the sun, and my cat started out with "crystals" progressed to diabetes. I don't want my animals to die so early, my grandparents never took their dogs to the vet, and they ate leftovers and lived very long lives. I want to take better care of them than my grandparents did, but I want to do what is right!!!!

Thanks!
