I agree, that the breed of dog isn't really so much of an issue. Certain breeds are more known for sensitive tummies, but at the end of the day, they have the same nutritional requirements, and are all "dogs."
I recommend a low carb food like EVO, Orijen, Welness Core, or Nature's Variety Instinct.
Definately stay clear of grocery store brands. If you've seen a commercial for it on tv, stay away from it. (with the exception of Blue)
