Yep.. Stay away from the purina, the pedigree, ALL the grocery store brands, really.. Science Diet, even though some vets recommend it, is HIGHLY overpriced corn kibble with very little of what dogs actually do need.
A raw diet (or the BARF diet) would be wonderful, but not everyone is up for that. If you are, that's awesome, and if you decide to feed a raw diet, the dog will LOVE it. I haven't ever seen a hungry dog turn up its nose at a raw meaty bone.. It seems like a lot more work than pouring kibble into a bowl, and it is, but once you get the hang of it and figure out your ratios, supplements, and what-have-you, it's a snap.
