Food is the same with dogs as it is with us lowly humanoids. I could eat like a pro, and die when I'm 60...while the person next to me could eat junk every day, smoke, drink what have you...and they'll live to 100. So, a lot of health can be a crap shoot. And genetics can cause things that nothing can prevent.
That said, I do believe a good diet with quality ingreds is good for any creature. The more natural a diet can be, the better, in most cases. I think one of THE most important things for a dog's health is activity...they should walk, run, play, fetch, feel loved. Dogs who get fat kinda break my heart...that is, when 'fat' is due simply to not moving (rather than from, say, a health issue).
I feed pre-made raw - usually Primal or Nature's Variety. I really love it for my kiddos. So much less processed than other foods, which I like. But, I think dogs can do so well on many different types of diets.
