Chances are if you see a commercial on TV for it, it stinks! lol. Go with something like Canidae, Blue Buffalo, Innova, or Solid Gold. Those are the ones that so far I have found are good by looking at the ingredients... I am sure there are many more... but mostly I go by...
1. No TV Commercials... Commercial brands stink... Especially Kibbles & Bits lol
2. No By Product in any part of the ingredients...
3. No corn, especially not as the first ingredient... because its just filler and hard for dogs to digest.
