I would not go over 18% for a pup because you can get all kinds of growing issues like knuckling over or pano for the big guys. As adults I would not feed over over 30% even my working dogs. I just add fat to add weight on not extra protein, the high the protein the harder the kidneys have to work. This is all personal preference but I would not feed the higher protein foods, you can feed some of the TOTW that is under 30% if you want grain free.
