Distilling questions brought up in the Halo and Orijen threads. In terms of the theory of protein percentages, calcium percentages in food and growth problems in puppies: can anyone point to a reliable reference, article etc? I have heard lots of anecdotes one way and the other (for example, high protein diet may cause panno), but would like to read any studies that might be out there (if there are any).
The link you posted is not a study at all. This is just one person's opinion based on that persons rationale. This is not proof that high protein does not produce problems in puppies.
If you don't like the info/links provided, perhaps you can do some searching on your own to answer your questions. Pls share what you find and in the meantime, if you are uncertain about the high protein question, stay with what you're doing now until that's resolved.
