I'm currently sitting in the vets office with my bulldog waiting on an IV. He has lost 5 lbs and can't keep down any food or water. I just purchased a new bag of grain free Nutro Natural Choice last week. My vet went to the a consumer affairs web site and there have been several complaints from dog owners that purchased this product in June. A couple of people mentioned that they called the company and their customer service reps stated that the formula has just changed (I have not verified that). My bully has been on this brand for three yrs with no problems. Since there are limited choices in grain free dog foods, I thought there could be a chance other bully owners may be using this product.
