We liked the bigger pieces in the Royal Canin GR because she eats fast, but the food didn't agree with Evie. She also didn't do well on Iams, Blue Seal, Diamond Natural, or raw. So far so fine on Natural Balance Bison and Potato. It's been a few weeks, now, that she's been on it. Interesting to me, though, just one sneaked bite of chicken and we were back in digestion purgatory for a week. I'm not one to jump to a food intolerance conclusion but she sure seems to have one from what I can tell.
