Here is an interesting grading of dog foods. I have seen it before and think that it is periodically updated.
What I feed (Dick Van Patten's Duck and Potato - Score 106) scored an A+. I have bred and showed dogs for 40 years and you need to keep up with the latest dog foods. They are ever changing. A long time ago I fed Science Diet. Those were in the days that it was well rated. Now the two listed both get F's.
Anyone here feed Purina? Wow, you can't get much lower than those F grades.
Have fun looking for your feed on this list. If you feed isn't on this list use the scoring system below and you can grade it.
