While you are right that Nutro is a good food, my dogs got very sick on it. It took awhile for the problem to start but both dogs would vomit bile on a daily basis. I was advised to increase the amount of feeding they received which worked for a few weeks and then the vomiting started again. Once again I did as advised and increased the amount of food they were receiving. It was okay for a few weeks and when they began vomiting at the same time everyday a few minutes apart from each other I changed their food back immediately.
