Solid Gold food does have pretty good ingredients for the most part.
I don't particularly like the company though, especially because they say it is AAFCO approved but it is always best to supplement dog food and their Seameal is great for that.
AAFCO approved dog foods do not need to be supplemented unless the dog has a specific need. If they think dogs need what is in their Seameal so badly, they need to put it in their food. It would bring them extra money though (to sell this separately).
So, their food is okay (for now) but the company itself isn't my favorite.
