I was just reading reviews on EVO dog food and several people blamed their dogs kidney problems/bad blood work results to the high protein, then they changed and everything went back to normal. Is this just a coincidence? We feed our dogs the best food we can afford (in my case Orijen Senior), are we risking the health of our dogs by feeding high protein foods? I have read the Orijen white paper, and read a bunch of stuff on how dogs need higher protein than most commercial foods contain. Any thoughts on this? I feel like I should stop feeding high protein food b/c I don't want to risk causing her issues. Last year we did blood work on her to have her tooth extracted, so I will do another in the summer to compare her numbers.
