I had fed my dogs nutro natural choice lamb and rice about 5 years ago. one day I came home from work and my beautiful Irish Setter was dead. I was very very upset. My wife and I took her to the vet to have an Icropsey done better known as an autopsey. 17 vets from a vey well known veterinary college all said it was due to the food we were giving her. So naturaly we stopped this food. we also had 2 other dogs to worry about. Our Irish setter had toxic gut from the famous nutro. Then I called the company they just ignored what I said and responded with it wasn t from their food.I have recently saw on the web site that this poisonous company that are Killing dogs all over the country have a multitude of class action law suits against them. All I can say is they need to be shut down before they kill any more of our family members. Asfar as the nutro reps are concerned for everyones sake they are just people that work weekends that make extra money to help push this dog food for the stores revenue.I hope everyone reads this article and takes my advice. I now have been using Blue Bufallo senior formula with no problems. although the transition period should be over a 2 week period. This is to get the dogs used to a healthy diet as opposed to the other junk food that is out there.To put simply its like eating fast food your whole life then eating a well balanced diet. this is done to prevent shock to your system.
