I realize you are doing the cooking, but thought this would help. Fromm's had this posted on their site:
The fifth ingredient includes brown rice. Like barley, brown rice is another quality grain that (once cooked) is fairly easy to digest.
The seventh ingredient lists white rice… a less nutritious form of brown rice in which the grain’s healthier outer layer has been removed.
This list didn't mention potatoes, but it did mention sweet potatoes. Hope it helps with your decision.
The fourth ingredient mentions sweet potato. Sweet potatoes are a good source of complex carbohydrates in a dog food. They are naturally rich in fiber, beta carotene and other healthy nutrients. Fromm Four Star Nutritionals Dry Dog Food | Review and Rating
