Just saw this.... Thanks for the recommendation, after much research we ended up going RAW and Blitz has never been better!maybe one of the acana grainless formulas would work. it is similar to orijen except for a little less meat content and lower protein levels. being made by champion as well i think many of us feel pretty confident with it. i think the grasslands formula is the only one with higher Ca levels....but the pacifica and wild prarie are ok.
