Dogs can only digest 24-26% protein. So if you buy 28% or higher, it goes out the back end. Waste of money, and of your backyard/kennel.
Not always true. It has been shown that a HARD WORKING dog can utilize up to 40% protein.
I *think* Science Diet has corn as the first ingredient -- or else it contains soybean. Look at your label and let me know. Thanks
