I use NutriSource also and have had no issues. I prefer the grain-free varieties. I had bad luck with Blue Buffalo and my dog ended up with diarrhea. My vet said it was a rich food and other dogs had been brought in for the same issue. If the dog is suddenly not eating after switching and has GI issues and is otherwise healthy and active, it is most likely the food. Also, rice in dog foods can cause gas and other issues in certain dogs as it is sometimes hard to digest and will sit and ferment in their bellies. So if your dog is having bad gas issues as well, I would consider switching to something without rice. My dog can’t handle rice either. Best of luck to you.
