The Victor Ultra Pro variety has the highest protein and the lowest fiber in the line. It has 42% protein, 22% fat and 2.7% fiber. The premium grain free that I’m using right now has 33% protein, 16% fat and 3.8% fiber. As for Earthborn Primative Natural, the fiber is even lower at 2.5%. I think the other varieties in the line are a little higher also. I’ve only tried the Meadow Feast and my dogs did not do well on it.
Both of these websites are very informative and easy to maneuver. You should check them out! Good luck.
