Thumbs Down on Solid Gold

Well my experiment with Solid Gold dog food is coming to a disappointing close. Despite the rave reviews given by most people it just isn't sitting well with two of my dogs, who have been having chronic diarrhea since being on it. I was hoping that they would become acclimated to the food and the problems would fade. Unfortunately that doesn't seem to be happening. Not sure where to turn next, I could just go back to Purina One. I did feed my dogs Nutro at one point, which is supposed to be a good dog food, I may try that.
