Pet Food Survey What do you feed your dog and/or cat?

I've been wondering for years about what other people feed their dogs and cats. When I look at wet dog food all I can think of is cancer. I don't know if that is correct, but I just wonder if I fed my dogs homemade food their entire lives, would they fair better and live longer? What do you all think? Lately I've been using California Natural, but I'm just in a quandry as our dogs have allergies, growths, etc...
