Nutrilife and Raw diet protien content - Page 1

I'm starting to feed my 14 week old GSD puppy Nutrilife. I'm not shure about the protein content which states a 24% minimum. I'm afraid that the protein content may be exceeding 24% since to much protein will increase the chances for him to grow quicker promoting hip displaysia. Should I keep feeding him Nutrilife? Also, how do I calaculate the protein content of raw chicken in like feeding him?
